Hair testing is increasingly recognized as an effective method for identifying alcohol and drug consumption. Hair offers an extensive retrospective view of substance use by encapsulating biomarkers within the strands as they grow. When a sample is taken near the scalp, it can reflect alcohol and drug use over a period of up to three months. Hair is easy to collect, resistant to tampering, and straightforward to transport.
A 1.5-inch section of roughly 200 hairs (approximately akin to the girth of a #2 pencil) close to the scalp yields 100mg of hair, the preferred sample for both screening and confirmation processes. For EtG, additional tests, or when the panel exceeds 10, 150mg is advised. It is suggested to use a jeweler’s scale for precise specimen weighing. Should scalp hair be inaccessible, a comparable quantity of body hair can be used. Note that "head hair" refers exclusively to scalp hair, while "body hair" encompasses all other types, including facial and axillary hair.
Process Overview
The laboratory processing of a drug test result involves four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the procedure of entering a sample into a lab's database. This involves ensuring that the sample was correctly sealed and transported, generating a random LAN (Laboratory Accessioning Number), and completing any requisite data entry not covered by an electronic chain of custody system.
Screening is an initial rapid analysis for drug presence. While Screening offers a cost-effective method for ruling out drug use in the majority of cases, a positive result requires confirmation to be permissible in legal contexts. Any potentially positive samples flagged during Screening necessitate a secondary confirmation.
If a sample is marked as potentially positive during Screening, additional hair is extracted from the original sample for further preparation in the Extraction phase. Here, drug compounds are isolated from hair at a considerably lower concentration than seen in other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.
Confirmation of a positive screening result is accomplished through GC/MS, GC/MS/MS, or LC/MS/MS methods. Presumptively positive samples are washed prior to confirmation when necessary. The entire process, from Accessioning to Confirmation, is reviewed under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
