Hair testing is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair archives a long-term usage history of alcohol and drugs by capturing biomarkers within the strands as they grow. When harvested near the scalp, hair can offer a detection period of up to roughly three months for alcohol and drug consumption. It is easy to collect hair samples, they are relatively secure from tampering, and are straightforward to transport.
A sample measuring 1.5 inches in length, consisting of around 200 hairs (approximately equivalent to a #2 pencil in diameter) near the scalp, will yield 100mg of hair, which is the preferred quantity for analysis and verification. For EtG testing, additional screenings, or tests beyond 10 panels, 150mg of the sample is advisable. It is suggested to measure the sample using a jeweler’s scale. If there isn't sufficient scalp hair, an equivalent quantity of body hair can be utilized. Here, 'head hair' specifically refers to hair from the scalp, while 'body hair' includes all other types (such as facial, axillary hair, etc.).
Overview of the Procedure
The laboratory processing of a drug test outcome involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary step where a sample is integrated into a laboratory’s system. This step ensures the sample's integrity in sealing and shipping, assigns a random LAN (Laboratory Accessioning Number), and completes any missing data not entered through an electronic chain of custody system.
Screening involves conducting a rapid assessment to detect drugs. Although Screening provides a cost-effective way to eliminate drug presence in most samples, any positive screen must be confirmed for legal admissibility. Samples showing a presumptive positive in Screening need further confirmatory testing.
When a sample tests presumptive positive during the Screening phase, additional hair is extracted from the initial sample to prepare for the Extraction stage. At this stage, drugs are extracted from hair at much lower concentrations than with other tests (e.g., urine or oral fluid), thus making hair drug testing one of the most complex testing methodologies.
Confirmation of any positive screen result is done via GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with presumptive positive results undergo washing prior to confirmation as required. The entire process from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 accreditation standards.
