Hair Follicle Drug Testing

Hair Follicle Drug Testing
 
Hair Testing for a 90-Day Drug Use History


Hair Follicle Testing for drugs is the one of the only ways to get an in depth drug use assessment of up to 90 days in the past to determine if someone has been using. Since hair growth is fed by the bloodstream, the ingestion of drugs of abuse is revealed by analyzing a small sample of hair. NDDC’s testing method measures the drug molecules embedded inside the hair shaft, eliminating external contamination as a source of a positive test result. This is a great test for an employer or parent trying to determine possible long term drug activity.


Simple specimen collection and highly accurate results that meet the same reference standards as urine testing, it is becoming increasingly common for employers and the courts to ask for a Hair Follicle Drug Test. Testing for illegal substances in hair gives you a greater time frame of detection than urine, blood and saliva. And, you can often detect drugs in hair for several months - if not years, if the hair is long enough. Normally 90 days is all that is requested.


With a hair follicle test, there are no known methods for sample adulteration (hair washing will not dilute the sample). Because specimen collection can be directly observed, the risk of adulteration is even further reduced. In comparison to a urinalysis drug test, cocaine, PCP, opiates, and methamphetamine have proven hair analysis far more effective than urine testing in identifying low-level drug use over an extended period of time since these chemicals are normally out of the bloodstream in within 3-7 days. When compared with urine specimen testing, hair testing provides up to 2.5 times the number of positives and a longer detection window.


With NDDC we get the results back to you quicker: Negative results are reported within 24 hours of receipt at the laboratory, and positive results are confirmed using gas chromatography/mass spectrometry (GC/MS) or gas chromatography/mass spectrometry/mass spectrometry (GC/MS/MS) within 48 to 72 hours. Hair testing is also forensically defensible.
Hair follicle testing can test for the following classes and types of drugs:

  • Amphetamines:   (Amphetamine, Methamphetamine, MDMA (Ecstasy) and MDA (MDEA, Eve and 3,4 methylenedioxyamphetamine)
  • Opiates:    (Codeine, Morphine, 6-monoacetylmorphine Morphine including Heroin, Oxycodone, Hydrocodone and Hydromorphone)
  • Cocaine:   (Cocaine & Benzoylecgonine metabolites)
  • Marijuana metabolite:   (THC Carboxylic Acid metabolite)
  • PCP:   (Phencyclidine, Angel Dust)

These five drug classes are mandated for testing by the Federal Government
**Note** Alcohol can also now be detected in a hair drug test.
