Regarded as a robust method for identifying drug and alcohol consumption, hair testing has gained prominence. Hair retains a history of substances like alcohol by capturing biomarkers within the strands. When taken near the scalp, hair offers up to a 90-day detection timeframe for alcohol and drugs. Collection is straightforward, tampering is challenging, and shipment is convenient.
Acquiring a sample of 1.5-inch hair strands totaling around 200 strands—comparable to a #2 pencil—near the scalp yields 100mg, optimal for screening and confirmation. For tests like EtG, add-ons, or those exceeding 10 panels, 150mg is advised. Using a jeweler's scale is suggested for accurate weighing. Should scalp hair be unavailable, an equivalent quantity of body hair is acceptable. References to head hair pertain to scalp hair; body hair includes all other types (e.g., facial, axillary).
Process Overview
There are four primary steps in lab processing of drug test results: Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the start of processing a sample into a lab's framework. It involves confirming proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and fulfilling data entry beyond what's electronically provided.
Screening serves as an initial quick check for substance misuse. Although Screening isn't costly, it alone isn't court-valid unless a positive result is confirmed. Presumptive positives in Screening require secondary verification.
For presumptive positives from Screening, additional hair is extracted and readied for the Extraction phase. This stage involves drug extraction from hair, albeit at lower concentrations compared to other methods (e.g., urine or oral fluid), illustrating why hair drug testing is rigorous.
Positive screening results are confirmed via GC/MS, GC/MS/MS, or LC/MS/MS. Samples flagged as presumptive positives undergo washing before confirmation if necessary. The entire process, from Accessioning to Confirmation, undergoes review per the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
