Hair testing is increasingly recognized as an effective resource for identifying drug and alcohol consumption. The fibers of the growing hair strand capture biomarkers, providing a prolonged timeline for substance detection. Hair, especially when collected near the scalp, offers an approximately three-month detection period for both alcohol and drugs. Its collection is straightforward, challenging to tamper with, and convenient to ship.
A 1.5-inch sample consisting of roughly 200 hair strands (approximating the thickness of a #2 pencil) cut close to the scalp yields 100mg of hair, which is ideal for both screening and confirmation tests. For EtG, additional tests, or panels exceeding 10, a specimen size of 150mg is advised. To ensure accuracy, we suggest weighing the sample using a jeweler's scale. In the absence of scalp hair, an equivalent quantity of body hair can be collected. The term head hair refers specifically to scalp hair, while body hair pertains to all other types (such as facial and axillary hair).
Process Overview
The laboratory processing of a drug test result consists of four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step where a sample is entered into the laboratory’s system. This step includes confirming the sample’s secure sealing and proper shipping, assigning it a random LAN (Laboratory Accessioning Number), and completing any manual data entry not captured by an electronic chain of custody system.
Screening entails a rapid preliminary test for the presence of drugs. Though cost-effective for ruling out drug use in most samples, a positive screen must be confirmed to ensure it is admissible in legal proceedings. Samples that yield a presumptive positive result during Screening require further confirmation through a secondary process.
If a sample tests presumptively positive during Screening, additional hair from the original specimen is sourced and prepared for Extraction. In this phase, drugs are extracted from hair at concentrations far lower than in other methods (e.g., urine or oral fluid), explaining the complexity of hair drug screening.
Any positive screenings are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Samples identified as presumptively positive are washed before Confirmation as necessary. From Accessioning to Confirmation, the entire laboratory process undergoes evaluation under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO/IEC 17025 standards.
