Hair testing is increasingly recognized as an effective means for detecting substance use. By retaining biomarkers within its fibers, hair presents a comprehensive history of alcohol and drug consumption. If harvested near the scalp, the hair can reveal drug or alcohol usage over a span of up to three months. It is straightforward to collect, not easily tampered with, and convenient for transportation.
A sample of 1.5 inches, containing approximately 200 hair strands (akin to the diameter of a #2 pencil), yields 100mg, which is the optimal amount for both screening and confirmation. For tests involving EtG, additional components, or those exceeding 10 panels, a 150mg sample is advised. Using a jeweler’s scale to weigh the specimen is recommended. Should scalp hair be inaccessible, an equivalent quantity of body hair can be utilized. When discussing head hair, the reference is exclusively to scalp hair. Body hair, on the other hand, encompasses all other hair types (such as facial and axillary).
Process Overview
Processing a drug test result in a laboratory involves four main phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the introductory incorporation of a sample into the laboratory’s system. This step confirms the proper sealing and shipping of the sample, allocates a random LAN (Laboratory Accessioning Number), and finalizes any additional data input not captured by an electronic chain of custody system.
Screening acts as a preliminary assessment for the presence of drug abuse. Although cost-effective for ruling out drug use in the majority of cases, a positive screen must undergo confirmation for legal proceedings. Presumptive positive results from Screening do require secondary verification.
In the event of a presumptive positive result during Screening, extra hair is sourced from the initial sample for Extraction. Here, drugs are removed from the hair at reduced concentrations than other methods (like urine or oral fluid). This is why hair drug screening remains one of the most challenging methodologies.
Confirmation of any positive findings during Screening is conducted with GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all samples with presumptive positives are washed if necessary. The comprehensive laboratory process from Accessioning to Confirmation undergoes scrutiny under the CAP (College of American Pathologists) Hair designation and aligns with ISO / IEC 17025 standards.
