Hair testing is recognized as an effective means for identifying use of drugs and alcohol. By trapping biomarkers in the hair strand's growing fibers, hair provides a prolonged history of alcohol and drug use. When collected near the scalp, hair samples allow approximately a 90-day detection window for alcohol and drugs. This method is straightforward to collect, challenging to tamper with, and easy to transport.
A sample of 1.5 inches consisting of nearly 200 hairs (similar in size to a #2 pencil) nearest the scalp yields 100mg of hair, which is the preferred quantity for both screening and confirmation. For EtG, additional tests, and/or panels above 10, the advised amount is 150mg. Utilizing a jeweler’s scale to weigh the sample is suggested. If scalp hair is unavailable, a similar quantity of body hair might be used. When referencing head hair, it pertains only to scalp hair, while body hair includes all other types of hair (beard, armpit, etc.).
Process Overview
The laboratory processing of a drug test result involves four main steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial integration of a sample into a laboratory's system. This process verifies sample sealing and proper shipment, assigns a random LAN (Laboratory Accessioning Number), and completes any additional data entry not provided by an e-chain of custody system.
Screening performs an initial rapid assessment for drugs of abuse. While it is an economic method to rule out drug use in most samples, a confirmed screen is necessary for court admissibility. Samples with a presumptive positive result during Screening must undergo a secondary confirmation.
If a sample shows a presumptive positive in the Screening phase, additional hair from the original specimen is prepared for Extraction. At this point, drugs are removed from hair at a significantly lower concentration than in other methods (e.g., urine or oral fluid), rendering hair drug screening the most complex methodology to execute.
Confirming any positive screening result involves methods such as GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are washed before confirmation as necessary. The step-by-step laboratory process from Accessioning through Confirmation is audited under both the CAP (College of American Pathologists) Hair specification and accredited to ISO / IEC 17025 standards.
