Hair testing stands as a potent method for identifying drug and alcohol usage, offering long-term substance history by trapping biomarkers within the fibers of a growing hair strand. When sourced near the scalp, hair can present a detection window spanning up to approximately three months for alcohol and other drugs. Hair is straightforward to collect, offers resistance to adulteration, and is convenient for shipping.
A sample sized at 1.5 inches consisting of roughly 200 strands of hair (equivalent to a #2 pencil width), nearest the scalp, yields 100mg of hair, an ideal amount for screening and confirmation. For EtG, additional testing, and panels exceeding 10, it's advisable to use 150mg of the specimen. It is suggested to use a jeweler’s scale for weighing. Should scalp hair be unavailable, a comparable amount of body hair is acceptable. When head hair is mentioned, it exclusively refers to scalp hair. Body hair covers all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result is comprised of four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to initially processing a sample into the lab's system, including verifying proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing further data entry if not already addressed by the electronic chain of custody.
Screening constitutes a preliminary check for drugs of abuse. While affordable for excluding drug use in most samples, a positive screen mandates confirmation for court admissibility. Any samples yielding a presumptive positive in Screening require further confirmation.
If a presumptive positive arises during the Screening phase, additional hair is extracted from the primary sample for the Extraction phase. Here, drugs are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), underscoring the complexity of performing hair drug screening.
Confirmation of any positive screening results is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing prior to confirmation if necessary. The comprehensive laboratory process from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.
