Forensic Hair Analysis Drug Testing
[ EIA Press Release | EIA Questions & Answers | EIA Facts | EIA History ]
FORENSIC DRUG TESTING THROUGH HAIR IS NOW AVAILABLE

A new, scientifically researched and proven drug testing method is now being offered for legal, governmental, commercial, and private use through AAA Truth Verification Laboratories, Inc.

The method, is called Immunoassay of Hair and is the only test capable of revealing when certain illegal drugs were used, whether in small, medium, or large amounts. In addition, traces of drug use can be traced back for prior months or up to one year.

Stephen B. Laub, Forensic Criminologist with AAA Truth Verification Laboratories, states that there is a physiological and proven scientific basis for the accuracy of the this methodology. "Drugs enter the hair from the bloodstream, and remain there in proportion to the amount taken, not diminishing over time. Thus the test cannot be evaded and past patterns of drug use can be established," Mr. Laub explained.

Forensic Drug Testing of hair goes beyond establishing drug use, it reveals a historical pattern of drug use or non use, over a given time period in direct correlation to hair growth. This method of detecting drug use yields quantitative data which is extremely important in diagnosis and treatment of drug dependency.

Since its development, the science of measuring drugs in hair by application of immunoassay drug testing has been confirmed by independent laboratories in the U.S., Japan, Italy, and Germany. In Studies completed with the U.S. Navy, data from the Hair Analysis Drug Tests were used to measure the effectiveness of the U.S. Navy's drug rehabilitation programs. Currently, the test is also being utilized in a program funded by the National Institute of Justice to monitor probationers and parolees for compliance with the drug free conditions of their sentences.

Truth Verification Laboratories provides Forensic Hair Analysis Drug Testing through their network of affiliated offices throughout the United States and Foreign Countries. All Drug Testing is performed by and through a consortium of Certified and Licensed Drug Testing Laboratories. They have specialized in the formulation and implementation of Forensic Drug Testing policies and programs for corporate use, since 1977.

Immunoassay of hair is a new drug testing methodology which has proven to be an effective complement to current urinalysis testing. The process has the advantage that it can detect illegal drug use over a long period of time, (one month to years) and can indicate the relative amounts of specific drugs taken during a specific time period. It also has the added advantage of being a Non-Evasive and Non-Intrusive Drug Test which requires just a small amount of hair from the subject's head or body. There is no question about the source of the specimen, or problems with evidentiary chain of custody issues, as each specimen donor is conclusively identified prior to and during each specimen collection.

Cranial (head) hair grows at about 1 cm - 1.3 cm per month (1/2"). So, for example, a two to three inch length of hair would contain a record of the last four to six months of drug use. Other body hair is potentially usable in the tests, but hair from the head has the advantages of relatively rapid growth, and minimal intrusiveness. Drugs used by an individual can become detectable after seven to fourteen days, in the hair closest to the scalp.

Therefore hair analysis drug testing is not suitable for ascertaining whether an individual is presently under the influence of a drug during one to seven days after ingestion. Other testing methods, such as urinalysis or blood analysis are more suitable for that purpose.

What Forensic Hair Analysis Drug Testing can uniquely provide is a history of drug usage during the past months or years, including the level of use. The drug molecules remain for life in the hair donor's hair. As the hair grows out from the scalp, the drug molecules remain. By dividing the hair into sections by length, an accurate chronological time frame of drug use history of each subject (Donor) can be developed, utilizing 1.3 cm per month of hair growth.

Forensic Hair Analysis Drug Testing is the only drug testing method which can distinguish between a heavy chronic drug user, and a light occasional user who may only have been tested at an inopportune time. The test can indicate the levels of drug use by an individual during the past three months, a year, or more. Another advantage of the Forensic Hair Analysis Drug Test is that the specimens to be tested can be readily obtained from a subject (Donor) without violating a person's privacy. Unlike urinalysis testing, the sample cannot be diluted, substituted, or intentionally contaminated. Subject's cannot claim that they are "unable" to provide a sample.

The Forensic Hair Analysis Drug Test might prove to be more cost effective than current drug testing methodologies because it will be easier to defend in court, should the need arise. In legal attacks on drug testing, the issues of privacy, chain of custody, and confirmation that the hair specimen was from the donor, will not be a factor.

Forensic Hair Analysis Drug Testing should also eliminate subjecting individuals to "constant" monitoring for drug testing or treatment programs. A Forensic Hair Analysis Drug Test can replace constant/repetitive drug testing by other methodologies, which also makes Forensic Hair Analysis Drug Testing extremely cost effective.

Hair analysis technology to identify new drug detection is continually being researched. Forensic Hair Analysis Drug Testing is currently able to chart drug use history for substances such as: Cocaine, Marijuana, Opiates, (Phencyclidine (PCP), Ecstasy/MDMA, Methamphetamines, Amphetamines, Barbiturates, Benzodiazepines, Methadone, Oxycodone/Oxycontin, Tramadol, Meperidine, Fentanyl, and Sufentanil. Tests for detecting other drug metabolites, nicotine, and alcohol are presently under research and development, and should be available soon.

FORENSIC HAIR ANALYSIS DRUG TESTING

QUESTIONS AND ANSWERS

  1. Q. WHAT IS ENZYME IMMUNOASSAY (EIA)?

    A. A Proprietary method for detecting drugs in hair using Enzyme Immunoassay (EIA). EIA measures the drug molecules permanently entrapped in the hair which were metabolized following ingestion.

  2. Q. WHAT DRUGS CAN BE INCLUDED IN A HAIR ANALYSIS DRUG SCREEN?

    A. Cocaine, Marijuana, Opiates, (Phencyclidine (PCP), Ecstasy/MDMA, Methamphetamines, Amphetamines, Barbiturates, Benzodiazepines, Methadone, Oxycodone/Oxycontin, Tramadol, Meperidine, Fentanyl, and Sufentanil, and many other Drugs of Abuse. Several of these drugs were identified as illegal drugs in The President's Executive Order 12564 and are several of the drugs mandated for testing by the Federal Government.

  3. Q. WHAT TIME PERIOD DOES A FORENSIC TEST COVER?

    A. A forensic drug test covers a period of approximately 90 days. The hair specimen is cut as close to the scalp as possible and the most recent 1- 1/2 " of hair (3.9 cm) is tested (1.3 cm per month). Testing for 6 months, 9 months, or 12 months can also be completed. For a one month test 1/2" of hair is required.

  4. Q. HOW FAST DOES HEAD HAIR GROW?

    A. Scientific studies indicate and confirm that hair collected at the crown/vertex of the head grows on the average approximately 1/2" (or 1.3 cm) per month. This growth rate varies among donors (estimated at + or - 0.2 cm per month), consequently the same 3.9 cm length of hair can represent a different time period in each donor.

  5. Q. HOW MUCH HAIR IS NEEDED?

    A. A forensic drug test which utilizes GC/MS (Gas Chromatography and Mass Spectrometry) confirmation requires approximately 40 milligrams of hair, or approximately 50 to 75 strands of hair.

  6. Q. HOW SOON AFTER INGESTION USE CAN A DRUG BE DETECTED IN HAIR?

    A. It takes approximately 5 to 10 days from the time a drug is ingested for the drug metabolite to enter the hair follicle, and allow the hair follicle to grow above the scalp to allow for specimen collection.

  7. Q. HOW DOES HAIR ANALYSIS DRUG TESTING COMPARE TO URINALYSIS?

    A. The primary difference is the wider window of detection available with hair testing. Cocaine, Methamphetamines, Opiates, Amphetamines, Benzodiazepines Ecstasy/MDMA, PCP, and many other drug metabolites are rapidly excreted and usually undetectable in urine 72 hours after ingestion. The detection period for forensic hair analysis drug testing is limited only by the length of the hair sample, every 1/2" of length covers approximately 1 month (30 days). Additional advantages include non intrusive collection procedures, virtual elimination of test evasion, greater accuracy through test repetition capability. The combination of an increased window of detection and resistance to evasion makes Hair Analysis Drug Testing far more effective than urinalysis, in correctly identifying drug users, whether they are casual users or addicted drug users.

  8. Q. WHAT IS THE SHORTEST TIME PERIOD THAT CAN BE ACCURATELY EVALUATED?

    A. In most situations the standard time period is one month (30 days). Due to the variability of hair growth rates, hair drug testing is not generally used to go back in time to determine if an individual used drugs on a particular day or in a particular week.

  9. Q. CAN TESTS BE RUN ON PEOPLE WITH LITTLE OR NO HAIR?

    A. Yes, hair can be collected from several locations on the head and combined to obtain the required amount of hair. In addition, body hair can be used as an alternative to head hair.

  10. Q. DOES BODY HAIR GIVE THE SAME TYPE OF RESULTS AS HEAD HAIR?

    A. Body hair can be used to test for drugs. Body hair growth rates are considerably more variable and growth is slower than head hair. Therefore, it is difficult to accurately represent the exact time period covered for a forensic drug test using body hair.

  11. Q. CAN FINGERNAILS BE USED TO TEST FOR DRUGS?

    A. Yes, fingernails are made of similar keratin proteins found in head hair and have also been proven to entrap drugs. Fingernail clippings are inferior as a sample compared to head hair only because of the limited "time window" of the clippings compared to head or body hair, however, fingernails can be used to detect and confirm drug use by individuals who have virtually no hair on their body.

  12. Q. CAN HAIR COLLECTED FROM A BRUSH BE USED?

    A. Our testing laboratory and our Chain-of-Custody Procedures require that a hair specimen be collected directly from the donor, using proper Evidentiary Forensic Chain of Custody protocols that will withstand any legal challenge. The donor must initial the specimen container pouch to certify the authenticity of the specimen at the time of collection. The specimen is then sealed in a Evidentiary Chain of Custody Tamper Proof Package, which must also be signed and then sealed, by the donor.
    B. Arrangements for the collection of hair specimens by our Certified Medical Professionals can be arranged at our collection sites throughout the United States - call us toll free at 1-800-727-8846 for information about your closest location.

  13. Q. HOW DOES OUR LABORATORY ESTABLISH ITS CUT OFF LEVELS?

    A. The cut off levels are established by the minimum detection levels for GC/MS - Gas Chromatography/ Mass Spectrometry confirmation, which is the scientific method of confirming a POSITIVE result.

  14. Q. WHAT ARE THE DIFFERENCES BETWEEN THE FORENSIC HAIR DRUG TESTING CUT OFF LEVELS AND URINALYSIS CUT OFF LEVELS?

    A. In general, cut off levels for urinalysis have been established to reduce the possibility of an evidential false positive due to passive ingestion or inhalation of a particular substance. A true comparison of forensic hair analysis drug testing vs. forensic urinalysis drug testing cut off levels is impossible, because of the evidentiary metabolite contamination time, which differs greatly for each drug - (days, weeks, months, or years for forensic hair analysis drug testing vs only 1 to 3 days for forensic urinalysis drug testing). SAMHSA/NIDA's recommended cut off levels for forensic urinalysis tests are expressed in nanograms per milliliter (ng/ml) of urine. Forensic hair analysis drug testing cut off levels for most drug metabolites are expressed in nanograms per milligram (ng/mg) of hair, except for marijuana which is expressed in picogram per milligram, or nanogram per gram - resulting in more sensitivity in hair tests than urine tests.

  15. Q. DO OUR LABORATORIES PERFORM GC/MS CONFIRMATION ON ALL POSITIVE FORENSIC HAIR DRUG TESTING ANALYSIS RESULTS?

    A. Our testing laboratories provide confirmation for Cocaine, Marijuana, Opiates, Methamphetamines, Phencyclidine (PCP), Amphetamines, Benzodiazepines, Barbiturates, and many other Drugs of Abuse. We can also provide quantitative analysis to indicate the approximate concentration of the drug metabolite present in the donors specimen, on all drug metabolites except Marijuana, which is reported as negative or positive only.

  16. Q. CAN FORENSIC HAIR ANALYSIS DRUG TESTING BE AFFECTED BY CROSS REACTING SUBSTANCES SUCH AS OVER THE COUNTER MEDICATIONS?

    A. Immunoassay antibodies, similar to those used to test urine, are used for the initial screening test for drugs of abuse in hair, therefore the potential for substances such as over the counter medications to cause a false positive screening result does exist. To eliminate the possibility of reporting a false positive due to cross reactivity, our testing laboratory confirms all positive results utilizing GC/MS (Gas Chromatography/ Mass Spectrometry) confirmation. Extensive GC/MS studies have also shown that the antibodies used for Cocaine drug screening do not cross react with any other substances, or over the counter medications.

  17. Q. HOW EFFECTIVE IS FORENSIC HAIR ANALYSIS DRUG TESTING IN DETECTING DRUG USERS?

    A. In side by side comparison studies with urinalysis, Cocaine, Marijuana, Opiates, Methamphetamines, Phencyclidine (PCP), Amphetamines, Benzodiazepines, & Barbiturates, Ecstasy/MAMA Enzyme immuno assays (EIA) have proven forensic hair analysis drug testing far more effective than urine tests in identifying low level, or addictive drug use. For example, the marijuana hair drug test is extremely sensitive, and therefore will identify Marijuana use, but will not quantify use as to low, medium, or high (addictive) with regard to the results. The results will only be reported as positive or negative.

  18. Q. DOES EXTERNAL EXPOSURE TO CERTAIN DRUGS LIKE MARIJUANA OR CRACK SMOKE, AFFECT THE FORENSIC HAIR ANALYSIS DRUG TESTING RESULTS?

    A. Hair samples are washed extensively in a proprietary solution to remove external contamination from Cocaine, Marijuana, Opiates, Methamphetamines, Phencyclidine (PCP), Amphetamines, Benzodiazepines, Barbiturates, and many other Drugs of Abuse. If the initial Enzyme Immunoassay screen is positive and the wash ratios are outside the cutoff limits, our testing laboratory will conduct more extensive washing for more effective decontamination. In addition, it may also be possible to measure drug metabolite levels in the hair wash solution. If the wash kinetics and the metabolite levels do not eliminate a positive result due to external contamination, results will be reported indicating that the positive result may be due to external contamination. Marijuana does not follow the same wash patterns of other drugs. To rule out the possibility of external contamination for Marijuana, GC/MS confirmation for the Carboxy THC metabolite is automatically provided for all presumptive positive specimens.

  19. Q. DOES TREATMENT OF THE HAIR AFFECT TEST RESULTS?

    A. Commonly used hair products (e.g. shampoos, conditioners, sprays, mousses, gels, bleaching & perms or dying) have no significant effect on hair analysis drug testing results. In fact, normal hair washing helps to remove external contamination. Extensive bleaching, perming and dyeing may damage the protein matrix of hair allowing a portion of the drug from the hair to be extracted, lowering the final quantitative results with certain drugs. Treated hair can be readily identified from the wash ratios and/or staining procedure. Treated hair results will be reported indicating that the correlation between the extent of drug use and the quantitative results were affected due to specific treatments to the donors hair. At the time of specimen collection, the CCT Technician will determine if the matrix & condition of the specimen is suitable for forensic drug testing.

  20. Q. IS OUR INTERNAL CHAIN OF CUSTODY COMPARABLE TO THOSE USED IN URINALYSIS FORENSIC DRUG TESTING?

    A. Our internal chain of custody is modeled after the requirements for Forensic Drug Testing recommended by the SAMHSA guidelines, and meets or exceeds those used for urinanalysis.

  21. Q. WHAT IS DONE WITH THE EXCESS HAIR THAT IS NOT TESTED?

    A. The hair not used covering the time period being tested (i.e. three months equals 1-1/2" or 3.9 cm) is stored in the chain of custody sample acquisition pouch at the testing laboratory, in a secure locked storage area. Negative hair specimens are stored for one month. Positive hair specimens are stored for up to one year, or as state laws require.

  22. Q. HOW LONG ARE POSITIVE AND NEGATIVE TEST RESULT REPORTS KEPT ON FILE?

    A. All laboratory records are maintained at the testing facility, test results are kept on file for a two year period, or as state laws require.

  23. Q. HAS FORENSIC HAIR ANALYSIS DRUG TESTING BEEN INTRODUCED AS EVIDENCE IN COURT?

    A. Yes, hair analysis has been admitted as evidence in court and used in over 5,000 cases during the discovery stage, and subsequent trials. A recent publication in The Army Lawyer, recommends that, "an accused who questions a positive urinalysis test result should consider hair analysis along with traditional investigation and other scientific tools". This publication suggests that the military is now ready to accept Enzyme Immunoassay with GC/MS confirmation, as an alternative in the military courts to overcome the shortcomings of urinalysis.

  24. Q. IS FORENSIC HAIR ANALYSIS DRUG TESTING DEFENSIBLE IN COURT?

    A. The same scientific tools and principles that are generally accepted in the scientific community for urinalysis are used in analyzing hair (i.e. a standardized screening test followed by GC/MS confirmation). GC/MS confirmation of the initial screen is required to provide maximum reliability and defensibility in court. From transcripts of the discussion section at the National Institute on Drug Abuse conference on hair analysis, U.S. District Court Judge Jack B. Weinstein stated, "Under the more liberal federal rules of evidence (702, 703, and 704), I would, myself, favor admissibility (of the GC/MS results) provided there were very good assurances of a strict protocol with respect to laboratory work generally and substantial proof that, in this specific case, there was proper use of that technique, and that the Defendant had an opportunity to meet it". In an interview with the Bureau of National Affairs, James E. Starrs, professor of law and forensic sciences at George Washington University, expressed his view that the results of forensic hair analysis, when confirmed by GC/MS, are admissible under Frye v. U.S., as long as the tests are properly performed, since the basic techniques for forensic hair analysis drug testing are well established. He said "nothing about hair as a medium or the techniques used for analyzing it should preclude admissibility".

  25. Q. HAVE THERE BEEN RECENT COURT CASES WHERE FORENSIC HAIR ANALYSIS DRUG TESTING WAS UTILIZED?

    A. Yes, in the following recent cases the results of forensic hair analysis drug testing were admitted as evidence, and successfully utilized:
    1. Burgel vs. Burgel (matrimonial) N.Y.L.J. Nov. 2nd 1988, P.21, Col.3 (2nd Dept).
    2. Baby Boy L - Family Court Suffolk County N.Y. Docket A-256-92, decided 03/12/93 by Honorable Judge David Freundlich.
    3. People vs. Medina (749F Supp 59 (1990) Ruling made by Honorable Judge Jack B. Weinstein - US District Court - Brooklyn, New York.
    4. Forensic hair analysis drug testing was also used to decide the verdict during court trial of Washington D.C. Mayor Marion Barry.

Facts - Forensic Hair Analysis Drug Testing

Who is at risk when a pregnant woman uses drugs?

The Mother?

The Baby?

The Doctor?

The Hospital?

The Insurance Company?

All of the Above?

The Mother

Women who use drugs during pregnancy are at greater risk for premature births, experience more difficulties during labor and delivery, and are more likely to have post-partum health problems.

The Baby

Prenatal drug exposure can cause infants to be born with mental retardation, neurological damage, and physical deformities. In many cases, damage is irreversible. Sharp rises in infant mortality in certain areas of the U.S. are being attributed almost entirely to prenatal drug exposure - Meconium (the first stool of the newborn baby) can be accurately tested to identify any drugs that may have been ingested from the mother during pregnancy.

Insurance Companies

Hospital care for drug-damaged babies often runs into hundred of thousands of dollars - to millions of dollars- a huge expense often borne by the insurance company

Hospitals

Many infants who have suffered prenatal drug exposure are too damaged to go home and cannot be placed in foster care. They remain in the hospital not because there is more to be done for them there, but because there is no place for them to go. Hospital facilities are becoming overcrowded and staff overburdened trying to provide care for the increasing number of babies damaged by prenatal drug exposure.

Doctors

A large percentage of these costly tragedies could have been averted had medical personnel diagnosed the problem of drug abuse early in pregnancy and taken steps to prevent further drug use. If this identification is not made, and prevention not attempted, the doctor is exposed to liability.

DID YOU KNOW?

A single lock of hair (30-50 strands) taken from a pregnant woman on her first visit will let the doctor know whether she has used cocaine/crack, heroin/morphine, or PCP (angel dust) and many other drugs since becoming pregnant.

Immunoassay, is routinely used to detect drugs in urine and blood, is now being applied to hair to determine approximately when and at what levels drugs were used. This type of drug use history cannot be obtained from an analysis of blood or urine because drugs in body fluids are transient. But posited in hair in proportion to the amount taken, and remain there indefinitely. As long as the hair is there, so is the drug, in large or small quantities, depending on how much was taken.

Now that EIA (Enzyme Immunoassay) of hair is available, all a doctor or medical professional needs to do is clip a piece of hair and send it to our testing laboratory for testing to find out whether a pregnant woman's use of cocaine, heroin or PCP or other drugs, places her in a high-risk category.

Early diagnosis of drug use during pregnancy can lead to earlier treatment, and prevention of further drug abuse, thus reducing difficulties for mother, child, and attending medical personnel. This in turn will reduce the astronomical economic cost associated with drug-damaged babies, which currently are being borne by families, hospitals, insurance companies, and taxpayers.


WHAT YOU NEED TO KNOW - TO IDENTIFY DRUG USERS?

When a drug-using client comes to you, there are things you need to know. How heavy is the person's drug dependency? Has past use been occasional or chronic? Increasing or decreasing? Is one drug invloved, or several?

In the past, it may have taken days, weeks or months to get correct answers to these questions. Now it takes as little as 72 hours, and a single snippet of hair.

The test is called EIA--Enzyme Immunoassay of hair. EIA tells you more than what drugs happen to be in a user's system at the time of the test. It tells you whether a client has used PCP, heroin/morphine, or cocaine/crack in the past several months. It provides information on quantity and frequency of use. Clients have been known to forget what they've used, but their hair remembers. Drugs which have been deposited there remain, in proportion to the amount ingested. If the hair is still there, so is the drug residue (metabolite).

By doing an EIA test at intake, it is possible to know at the onset exactly what the client's drug use pattern has been. Such information, in the hands of a rehabilitation professional, can be enormously helpful in making treatment decisions, and in breaking down denial. EIA can also be used for monitoring and follow-up. Because drugs in hair are permanent, EIA does not permit a user to evade this detection by abstaining from drugs for a few days prior to the test. This eliminates the need for random testing. Scheduled hair specimen collections at appropriate intervals can be used to determine whether cocaine, marijuana, heroin, PCP , or other drug use occurred at any time during the period being monitored.

EIA, by providing objective data to support the medical professional's diagnosis, contributes more to rehabilitation than any other type of drug test.


History-EIA-Forensic Hair Analysis Drug Testing

A lesson in history

If you are testing for drugs, you may want to know more than what a person took most recently. You may want to know their drug abuse history. Because it's not just what they took that matters, it's how long they've been taking it.

Until now, it's been impossible to establish a person's long-time drug use history through drug testing. Urinalysis testing gives an accurate account of drugs present in the body at the time of testing, but what about other times?

What about the need to know whether a person has used illegal drugs over a period of weeks, months, or during the past year? What about the need to know whether an incident of drug abuse was a one-time event or part of an ongoing behavior pattern?

There hasn't been a cost-effective way to obtain this information in an objective scientific format.

Until now.


Introducing drug testing by hair analysis - EIA

Industry experts have long awaited the introduction to the private sector of a highly respected technique that allows chemists to check human hair for trace elements of chemicals that were once in the body.

The scientists and human resource managers agree: EIA is a revolutionary new process that is changing the way medical professionals think about drug testing.


The power of an idea whose time has come

EIA is based on a very simple scientific fact. As the blood circulates through the body, it passes through the roots of the hair. If there are drugs, trace amounts of the drug become trapped in the cortex, or central core of the hair. Those traces remain in the hair as it grows out from the body.

Since hair grows at a predictable rate (about 1.3 cm per month - approximately 1/2" inch), the distance of a drug trace from the root of the hair can tell us how long ago the drug was in the system.

In a sense, the hair acts like a chemical tape recorder, keeping a living record of substances that passed through the body.


Avoid the privacy problem

With the EIA Drug Testing Method, you cut a few strands of hair from the scalp of the test subject. There's not the embarassment associated with giving or collecting a urine sample.

And since the hair specimen is taken directly from the subject's head, there's no question of the source of the specimen.

Our laboratory tests the segments representing the time periods you request. If you are interested in looking for drug usage during the last two months, our laboratory can test for specific time frames, by sectionalizing the hair specimen.

EIA can report results for a selected time period. Our laboratory can also provide concentration levels of drug metabolites in quantative amounts, in order to determine if a person is a casual user, a repetitive user, or an addicted drug user.

EIA gives you results broken down into the time periods you select. What's more it gives you concentration levels of the drug, so you can differentiate between light, medium or heavy usage over each period of time.

With EIA, you get a picture of the individual's true drug behavior.


When to use Forensic Hair Analysis Drug Testing

Use urinalysis drug testing to determine the presence of a drug in the body at a specific time - usually one to three days.

Use forensic hair analysis drug testing to determine a person's drug use history.


The importance of Forensic Hair Analysis Drug Testing

Most legal challenges to drug testing are to the identity of the sample itself. The courts require that the sample be identified beyond a doubt. Since the hair specimen is cut directly from the donor's body, and then verified by the donor, there can be no doubt about the origin of the specimen.

But we don't stop there. We know how important it is that our work be unimpeachable. That's why our evidentiary chain of custody program is so important.

From the moment the subject and medical technician seal the hair specimen and certify its identity, exacting legal procedures are followed with two goals in mind.

The first is to make sure the specimen is correctly identified at every point in its history.

The second is to make sure that the historical record of that identity can be proven in a court of law.

Evidentiary Chain of Custody is a painstaking process developed over centuries by law enforcement officials to protect evidence. Specimens are sealed by both the donor and the certified collection technician, and signed for every point in transit.

When they arrive at our testing laboratory, specimens are identified and bar coded,and tracked throughout the entire testing process. Finally, positive specimens are stored for two years, or as state law requires, should they be needed as evidence.


EIA Forensic Hair Analysis Drug Testing can also be used in screening for . . .

Rehabilitation Programs (to test compliance with parole or probation or to ensure recovering addicts are staying off drugs)

Psychiatric Hospitals (to monitor new arrivals for psychotic conditions caused by PCP or other drugs)

Children's Hospitals (to determine treatment for newborns who may have been exposed to drugs in the womb)

Insurance Industry (to look for signs of drug abuse affecting policy issuance)


Why choose EIA Forensic Hair Analysis Drug Testing

EIA is the best and most informative drug testing procedure in existance.

EIA has been offered for years to specialized organizations like the United States Navy, the U.S. Probation Office, state hospitals and public and private alcohol rehabilitation programs.
