Hair analysis is now recognized as a significant approach for identifying drug and alcohol consumption. Hair captures a long-standing record of alcohol and drugs by embedding biomarkers within the fibers of the actively growing hair strand. When sourced near the scalp, hair offers a roughly 3-month detection period for alcohol and drugs. Hair is effortless to obtain, relatively hard to tamper with, and straightforward to transport.
A 1.5-inch segment of around 200 strands of hair (comparable to the girth of a #2 pencil) nearest the scalp will yield 100mg of hair, the ideal quantity for analysis and validation. For EtG, supplements, and/or tests exceeding 10 panels, 150mg of the sample is suggested. We suggest measuring the specimen on a precision balance. If scalp hair is absent, a similar amount of body hair can be used. By "head hair," we mean only scalp hair. "Body hair" encompasses all other hair (facial, underarm, etc.).
Process Overview
The primary four stages in the laboratory procedure of generating a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the primary handling of a specimen within a lab’s system. It entails confirming the sample was securely sealed and sent correctly, allocating a random LAN (Laboratory Accessioning Number), and finishing any added data entry absent from an electronic chain of custody protocol.
Screening serves as an initial swift evaluation for drugs. Though Screening is an economical method to exclude drug presence in the majority of samples, a positive result needs verification to be court-admissible. Any samples that show presumptive positive findings in Screening necessitate additional confirmation.
On registering a presumptive positive at the Screening phase, further hair is drawn from the original sample and set for Extraction. Here, drugs are retrieved from hair at notably lower concentrations than other methods (e.g., urine or oral fluid), which underlines why hair drug screening is one of the most technically challenging methods.
Verification of any positive screening outcome is performed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicating presumptive positives undergo washing prior to confirmation if required. The entire lab process from Accessioning to Confirmation is examined under both CAP (College of American Pathologists) Hair standards and the accreditation to ISO / IEC 17025 norms.
