Hair analysis has emerged as an effective method for identifying substance and alcohol consumption. Hair encapsulates a prolonged timeline of substance activity by embedding markers within the strands as they grow. When obtained near the scalp, hair can provide a detection window of roughly three months for alcohol and various substances. Collection of hair is straightforward, somewhat resistant to tampering, and easy to transport.
A 1.5-inch segment comprising around 200 hairs (resembling the size of a #2 pencil) nearest to the scalp provides 100mg, the preferred amount for both screening and verification processes. For EtG, additional tests, or panels above ten, 150mg of the sample is advised. It’s suggested to measure the sample on a jeweler’s scale. If scalp hair is not present, similar quantities of body hair can be gathered. When we discuss head hair, it specifically refers to scalp hair, while body hair encompasses all other types (e.g., facial, axillary, etc.).
Process Overview
The laboratory analysis of a drug test result involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary processing of a sample into a lab’s database. It involves ensuring the sample was appropriately sealed and conveyed, generating a random LAN (Laboratory Accessioning Number), and completing any further data entry not supplied by an electronic custody trail system.
Screening is a preliminary assessment for the presence of drugs. Although it serves as a cost-efficient method to identify drug usage in most samples, a positive screen must be validated for legal acceptability. Samples that are provisionally positive in Screening necessitate additional confirmation.
If Screening indicates a positive result, more hair is extracted from the initial specimen for the Extraction phase. This phase involves retrieving substances from hair at significantly lower concentrations than other methods (such as urine or saliva), accounting for hair analysis being the most complex methodology.
Positive screenings are confirmed through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation as necessary. From Accessioning to Confirmation, the entire lab procedure is evaluated under both the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation standards.
