Hair testing has emerged as an effective method for identifying drug and alcohol consumption. Hair captures biomarkers within the fibers of the maturing hair strand, offering a protracted history of alcohol and other drug use. When collected near the scalp, hair can reveal a detection period of up to about 3 months for alcohol and other substances. The collection of hair is straightforward, relatively resistant to tampering, and convenient to transport.
A 1.5-inch piece consisting of 200 hair strands (equivalent to a #2 pencil's width) nearest to the scalp provides 100mg of hair, the optimal quantity for screening and verification. For EtG, additional tests, and/or beyond 10 panels, 150mg of the sample is suggested. Measuring the sample with a jeweler’s scale is advised. If there's no scalp hair, an equivalent volume of body hair can be used. "Head hair" specifically refers to scalp hair. "Body hair" encompasses any other hair types (such as facial, axillary, etc.).
Process Overview
The drug testing lab process comprises four major steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning signifies the initial processing of a sample within a laboratory’s system. This step confirms the sample's proper sealing and shipping, assigns it a random LAN (Laboratory Accessioning Number), and completes any further data not supplied by an electronic chain of custody system.
Screening conducts a preliminary swift check for substance abuse. While it is an economical means to exclude drug use in most samples, positive screens must be verified to hold up legally. Samples presumed positive at Screening necessitate an additional confirmation.
If a sample tests presumptively positive during Screening, additional hair is extracted from the original sample and prepared for Extraction. At this step, drug substances are drawn out from hair at significantly lower concentrations than other methods (for example, urine or oral fluid), rendering hair drug screening the most complex methodology to implement.
Confirmation of any positive screening result is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive outcomes undergo washing before confirmation if required. The comprehensive lab process from Accessioning through Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
