Seen as a robust method, hair testing effectively detects substance abuse, with the ability to trace both drug and alcohol consumption over extended periods by encapsulating biomarkers within the hair fiber's growing strand. When gathered close to the scalp, hair can offer roughly a 3-month detection period for substances. Hair is easy to collect, relatively hard to tamper with, and simple to dispatch.
An ideal 1.5-inch sample, containing around 200 hairs (approximately matching the size of a #2 pencil), nearest to the scalp provides 100mg of hair, suitable for both screening and verification. For EtG, additional tests, or those exceeding 10 panels, 150mg of the sample is suggested. It is recommended to measure the sample weight using a jeweler’s scale. Should scalp hair be absent, a comparable quantity of body hair may be used. Head hair specifically refers to scalp hair; body hair includes all other types (facial, axillary, etc.).
Process Overview
The core steps in laboratory processing of drug test results include Accessioning, Screening, Extraction, and Confirmation.
Accessioning deals with initially processing a sample into a laboratory's system, ensuring proper sealing and dispatch of the sample, assigning a unique LAN (Laboratory Accessioning Number), and completing any supplementary data entry not covered by an electronic chain of custody system.
Screening provides a preliminary check for drug presence. Although cost-efficient in ruling out drug usage among most samples, a positive screening necessitates confirmation for court admissibility. Presumptively positive samples in Screening demand further verification.
Should a screening return positive, extra hair is taken from the sample for Extraction. Here, drugs are drawn from hair at much lower concentrations than other methods (e.g., urine or oral fluid), which highlights the complexity of hair drug screening.
Positive screening results are validated via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples undergo necessary washing prior to confirmation. The complete laboratory cycle from Accessioning to Confirmation is reviewed under CAP (College of American Pathologists) Hair designation, as well as compliance with ISO / IEC 17025 standards.
