How It Works

Frequently Asked Questions:


What is hair testing?
Since hair growth is fed by the bloodstream, the ingestion of drugs of abuse is revealed by analyzing a small sample of hair. Our testing method measures the drug molecules embedded inside the hairshaft, eliminating external contamination as a source of a positive test result. Hair testing results cannot be altered with shampoos or other external chemicals.

How accurate is hair testing?
Hair testing is the most accurate and effective method of finding users of drugs of abuse. Using a small sample of hair cut at the scalp, hair analysis evaluates the amount of drug metabolites embedded inside the hair shaft.

The testing technology is designed to show the presence of drug levels which would only be consistent with the ingestion of drugs. All samples are tested using a radioimmunoassay screen. Before any positive test result is reported, the sample is subjected to a second, confirmatory test using gas chromatography/mass spectrometry (GC/MS), considered the gold standard for forensic drug testing.

* This data was acquired from various academic studies with admitted drug users and are thus subject to numerous sources of variability (e.g. purity, inadequate self-report, etc.). Please use this graph as a guide only and not as exact numerical interpretation. This information may be useful to help establish an appropriate type of rehabilitation program or to compare two separate time periods.

What drugs does HairConfirm™ screen for?
HairConfirm™ screens for five different drug classes: Cocaine (cocaine & benzoylecgonine), Marijuana, Opiates (Codeine, Morphine & 6-monacteyl morphine), Amphetamine (Meth/amphetamine & Ecstasy) and Phencyclidine (PCP, angel dust).

The fact that HairConfirm™ screens for the five most popular drug classes is a major advantage to parents. Many parents use this test to detect possible marijuana use but some do not believe that marijuana is ‘that’ harmful. However parents should be aware that teens who start out as casual marijuana users are more likely to use harder drugs such as ecstasy, meth and cocaine than teens who do not. So it is important to test your child at the first signs of suspicious behavior that could be the result of drug use and even if there are no signs. HairConfirm™ is a very effective drug-prevention tool and will help in aiding parents to enforce a drug-free policy in their home.

In some cases, when the donor has used marijuana, a hair drug test, including HairConfirm™, may be unable to detect the THC metabolite due to the fact that the metabolite was unable to bind with the hair shaft. This can be caused by the type/quality of the marijuana smoked/ingested, or by what it has been mixed with, e.g. tobacco. As a result, the result for marijuana may be negative.

What time period does the HairConfirm™ test cover?
HairConfirm™ will detect drugs for a period of 90 days. The test requires a hair sample of 1.5 inches in length. Each 0.5 inch represents 30 days.  The hair sample must be cut as close to the scalp as possible and the most recent 1.5 inches are tested.

How does Hair Testing compare to urinalysis?
When compared to the more traditional forms of testing, i.e. urine testing, hair samples can detect a longer period of drug use. With urine, most drugs are undetectable if urinalysis is done more than 2-3 days after use, with the exception of marijuana, which may be detected for a slightly longer period of time. After the 2-3 day period, a urine donor will test negative and slip through the urine screening process. With hair samples, the only time limitation for detecting drug usage is imposed by the length of the donor’s hair. Each ½ inch of head hair provides a 30-day history of drug use. The standard for the industry is to test 1.5 inches, which provides a 90-day history of the donor’s drug use.

How effective is Hair Testing in detecting drug users?
In side-by-side comparison studies with urinalysis, hair drug testing has uncovered significantly more drug use. In two independent studies, hair drug testing uncovered 4 to 8 times as many drug users as urinalysis for evidence of drug use.

Can hair be affected by cross-reacting substances such as over-the-counter medications?
Enzyme-immunoassay antibodies (EIA), similar to those used to test urine, are used for the initial drug screening 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 result due to cross-reactivity, our laboratory performs Gas Chromatography Mass Spectrometry (GC/MS) for all specimens that screen positive.


How fast does head hair grow?
Studies indicate that head hair grows on average of 0.5 inches (1.3cm) per month. This growth rate varies slightly (estimated at ± 0.2 cm per month), consequently there is some (± 1 week) time variation possible. Head and body hair do not grow at the same rate; body hair grows at a slower rate.

How soon after use can a drug be detected in hair?
It takes approximately 4-5 days from the time of drug use for the affected hair to grow above the scalp. Body hair growth rates are generally slower and cannot be utilized to determine a timeframe of drug use.

Can tests be run on people with little or no hair?
Hair can be collected from several head locations and combined to obtain the required amount of hair.  If the head hair is too short, body hair can be used as a substitute. If body hair is used the timeframe represented by the test is approximately one year due to the different growth pattern in hair below the neck. NOTE:  DO NOT mix head and body hair.

How do I know I have enough hair?
We ask you to submit 1.5 inch length of hair and 90-120 strands at least. More strands are needed if the hair is less than 1.5 inches long or if hair is extremely thin. Collect from several locations if hair is very short.

The testing is done measuring the weight of the hair. We need at least 150 mg of hair ( that is 0.15 grams that is 0.00529 ounces) to perform the test.

PLEASE NOTE: HairConfirm™ is not responsible if hair submitted is less than that amount. The test can not be performed with less hair and will report as Quantity not sufficient (QNS)

What is the shortest time period that can be accurately evaluated?
The minimum time period is approximately one month (0.5 inch).

Can hair collected from a hairbrush be used?
No, we do not recommend taking a hair sample from a brush or any other source (e.g. pillow, clothing) as the sample may be contaminated and there is no guarantee that the hair is from your child. The laboratory will reject a hair sample if it is not collected and prepared as per the instructions.

How does the test work?
Using the detailed instructions as a guide, collect a hair sample of approximately 90-120 hairs.  Mail the hair sample to our laboratory, using the pre-addressed envelope provided. The laboratory will analyze the hair sample for evidence of drug use. Using your HairConfirm™ Specimen ID number, passcode and email address, you must register your test once you have mailed the samples to the laboratory.

What cut off levels are used by HairConfirm?

HairConfirm™ Drug Test follows the cut-off levels generally accepted industry-wide. These levels are based in part by minimum detection levels for GC/MS confirmation. The cut-off level for each drug varies (depending on the type of drug) and is listed below.

Although HairConfirm™ Drug Tests are designed to detect a very small amount of a drug in the hair, if the amount is below the established cut-off level, you may test negative for that drug even though you may have taken the drug.

Drug Class Screening Cut off level Confirmation Cut off level
Amphetamines- Amphetamine, Methamphetamine & Ecstasy 500 pg/mg hair 500 pg/mg hair
Cocaine- Cocaine & Benzoylecgonine 500 pg/mg hair 500 pg/mg hair
Opiates- Codeine, Morphine & 6-MAM (Heroin Metabolite) 300 pg/mg hair 300 pg/mg hair
Phencyclidine- PCP 300 pg/mg hair 300 pg/mg hair
Marijuana- Carboxy- THC 1 pg/mg hair 0.3 pg/mg hair

Pg/mg= picogram per milligram of hair

Does the lab provide Gas Chromatography Mass Spectrometry (GC/MS) confirmation for all positive results?
Yes GC/MS confirmation is performed on all positive results to avoid any false positives


How will I obtain the results?
After you have mailed the hair sample, you must register your test at to obtain your results. You will need your Specimen ID number, passcode and email address to register.

The results will be available approximately 2-3 business days after the hair sample is received by the laboratory. Please note that lab processing times may vary. If you have any questions about how to read the results, please go to the Help section on our website, where you will find answers to our most frequently asked questions.

How will I read the results?
The results will indicate a positive or negative result for each drug class. In addition, when a donor tests positive, the result will provide an assessment of hair dose response to identify whether the donor is a low (occasional), medium (weekend, daily) or high (constant) user (not including Marijuana).

What does the report look like?

Will the test result remain confidential?
Yes, the results are kept completely confidential and are for your use only. No names or social security numbers are used in the testing process. The only identification is the specimen ID number provided with the kit.

Does external exposure to certain drugs, like Marijuana or crack smoke, affect the hair test results?
To rule out the possibility of external contamination, HairConfirm™ testing (where appropriate) looks for both parent & metabolite (bi-product) of drug usage. For Marijuana analysis, our laboratory detects only the metabolite (THC-COOH). This metabolite is only produced by the body and cannot be an environmental contaminant.

Does hair color affect results?
Hair color is determined by the amount of melanin in the hair. It has been shown experimentally, through actual hair samples, as well as determined in court, that hair color has NO basis in fact.

Why did Marijuana (THC) show up negative?
In some cases, when the donor has used marijuana, a hair drug test, including HairConfirm™, may be unable to detect the THC metabolite due to the fact that the metabolite was unable to bind with the hair shaft. This can be caused by the type/quality of the marijuana smoked/ingested, or by what it has been mixed with, e.g. tobacco. As a result, the result for marijuana may be negative. This is only the case with THC and not with the other illicit drugs (COC, Heroin..etc). In most cases with adults it takes smoking 5-6 full joints in order for enough of the drug to “stick” to the hair to show a positive- this is an average number. If the amount consumed by the individual was less than that it might not show up in a drug test.

In the case where a long term THC use is present (like medical marijuana) sometimes the individual’s body can create a masking agent that would hinder the marijuana in a drug test.

Statistics have shown that teenagers who have used marijuana are more likely to use other potentially more dangerous drugs, than those who have never used marijuana. So if you suspect the individual may be using marijuana it is important to remember that you are also testing for those illicit drugs.

Do you have any support services after the results?
