Hair assays have emerged as an effective method for identifying drug and alcohol usage. Hair strands offer a prolonged history of substances by capturing biomarkers within the growing strands. When clipped near the scalp, hair samples provide up to a 90-day detection period for alcohol and various drugs. Hair collection is straightforward, relatively challenging to tamper with, and simple to transport.
A sample size of 1.5 inches, consisting of roughly 200 hairs (equivalent to the diameter of a #2 pencil) closest to the scalp delivers 100mg of hair, which is optimal for testing. For EtG extensions and/or tests exceeding 10 panels, 150mg of the sample is advised. Utilizing a jeweler’s scale to weigh the specimen is recommended. If scalp hair is not obtainable, a comparable amount of body hair can be used. The term head hair pertains exclusively to scalp hair, while body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The four crucial steps in lab processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves initial sample processing into the lab system. This process includes verifying proper sample sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing alternative data entry absent in an electronic chain of custody protocol.
Screening involves a preliminary assessment for drugs of abuse. Although Screening is cost-effective for excluding drug use in most samples, a positive result requires confirmation for legal admissibility. Samples presumptively positive during Screening necessitate additional verification.
If a sample shows presumptive positivity during Screening, additional hair is extracted from the original specimen for Extraction. Here, drugs are isolated from hair at significantly lower levels than in other methods (e.g., urine or oral fluids), which is part of the challenge of conducting hair drug analysis.
Confirming a positive screening outcome employs GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo a wash before necessary confirmation. The entire lab procedure from Accessioning to Confirmation is reviewed under both CAP (College of American Pathologists) Hair certification and ISO/IEC 17025 standards accreditation.
