Hair analysis is increasingly recognized as an effective means of detecting substance use, including alcohol. The fibrous nature of hair strands captures drug and alcohol biomarkers, providing a comprehensive profile of substance intake spanning months when collected close to the scalp. This method is straightforward to collect, resistant to tampering, and easy to transport.
Collecting a 1.5-inch hair sample, consisting of roughly 200 strands (comparable in size to a #2 pencil), from near the scalp yields 100mg of hair, which is optimal for both screening and confirmation processes. For EtG, additional analyses, or panels exceeding 10 substances, a specimen of 150mg is advisable. The specimen should ideally be measured using a jeweler's scale. If scalp hair isn’t available, an equivalent amount of body hair is acceptable. "Head hair" specifically refers to scalp hair, while "body hair" encompasses all other types (such as facial or axillary hair).
Process Overview
The laboratory analysis of a drug test involves four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails integrating a sample into the laboratory's system. This step involves ensuring the sample’s proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and finalizing any necessary data entry not covered by an electronic chain of custody system.
During Screening, a preliminary evaluation for drug presence takes place. Screening is an economical method to dismiss drug use in many cases; however, a positive screen mandates confirmation for legal admissibility. Presumptively positive samples identified in Screening require additional confirmation.
When a Screening result is presumptively positive, additional hair from the original sample is utilized for Extraction, where drugs are extracted at a lower concentration than in other methods (such as urine or oral fluid), making hair drug testing one of the more complex methodologies.
Confirmation of any positive Screening finding is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to Confirmation, all presumptive positive samples undergo necessary washing. The full laboratory sequence from Accessioning to Confirmation holds validation by the CAP (College of American Pathologists) Hair designation and meets ISO / IEC 17025 standards.
