Hair analysis has emerged as an effective means for identifying alcohol and drug usage. It provides an extended historical record by embedding biomarkers within the strands of growing hair. Hair samples gathered near the scalp can offer up to a 3-month detection period for substances like alcohol and drugs. The process of collecting hair is straightforward, generally tamper-resistant, and convenient for shipping.
A 1.5-inch section of roughly 200 hair strands (similar in size to a #2 pencil) from near the scalp will yield 100mg, which is the optimal quantity for screening and verification. For tests like EtG, additional panels, and tests exceeding 10 panels, 150mg of hair is advisable. Using a jeweler’s scale to weigh the sample is suggested. If head hair isn't obtainable, an equal volume of body hair might be used. When discussing head hair, it is specifically scalp hair. Body hair includes all other hair types (such as facial and axillary hair).
Process Overview
The laboratory procedure for processing drug test results involves four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the commencement phase where a sample is entered into the laboratory system. It involves ensuring that the sample was properly sealed and transported, assigning it a unique LAN (Laboratory Accessioning Number), and performing any additional data entry if not provided by an electronic chain of custody system.
Screening comprises a preliminary quick assessment for drug usage. While it is a cost-efficient method to exclude drug usage in most samples, a positive screen must be confirmed to stand in legal settings. Samples that yield a presumptive positive in Screening require further confirmation.
If a sample appears positive in the Screening phase, more hair is extracted from the initial sample and readied for Extraction. During this step, drugs are isolated from hair at comparatively lower concentrations than other methods (like urine or oral fluid), underscoring why hair drug analysis is the most challenging methodology.
Confirming a positive Screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Any presumptive positive samples are cleansed before confirmation as required. The entire laboratory operation from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
