Hair testing is widely recognized as an effective means to identify the use of drugs and alcohol. By capturing biomarkers within the fibers of the growing hair strand, hair offers a prolonged timeline of alcohol and other drug usage. Collected near the scalp, hair can furnish up to a 3-month substance detection period. Its ease of collection, resistance to tampering, and straightforward shipping make it a practical choice.
A sample of 1.5 inches consisting of roughly 200 hair strands (comparable to the girth of a #2 pencil) closest to the scalp yields 100mg of hair, ideal for screening and confirmatory purposes. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of the specimen is advised. We suggest weighing the specimen using a jeweler’s scale. Should scalp hair be unavailable, a comparable quantity of body hair may be used. The term 'head hair' specifically pertains to scalp hair. Meanwhile, 'body hair' covers all other hair varieties (facial, axillary, etc.).
Process Overview
The drug test result processing in the lab comprises four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the preliminary incorporation of a specimen into the lab's framework. It ensures the proper sealing and shipment of the sample, allocates a random LAN (Laboratory Accessioning Number), and concludes any pending data input absent from an electronic chain of custody system.
Screening commences with a rapid inspection for substances of misuse. While it is a budget-friendly approach to dismiss drug use in most cases, a positive screen necessitates confirmation for it to be viable in a legal context. Any samples that are ostensibly positive during Screening require an additional confirmation.
In cases where Screening indicates a presumptive positive result, further hair is extracted from the original specimen for the Extraction phase. Here, drugs are withdrawn from hair at notably lower concentrations than other procedures (such as urine or oral fluid), underscoring why hair drug screening presents a methodological challenge.
Confirmation of any positive screen outcome is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo washing prior to confirmation when essential. The entire lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair classification and compliance with ISO / IEC 17025 standards.
