Hair analysis is increasingly recognized as a robust method for detecting drug and alcohol consumption. Hair captures a comprehensive historical record of substance use by embedding biomarkers within the growing hair's texture. When clipped near the head, hair can offer an approximate 3-month period of detection for alcohol and various drugs. Hair is easy to gather, relatively resistant to tampering, and straightforward to transport.
A 1.5-inch segment consisting of around 200 hair strands (comparable to the width of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the perfect sample size for both screening and verification. For EtG, supplemental tests, and/or panels exceeding 10, a 150mg sample is advised. It's preferable to gauge the sample using a jeweler's scale. Should scalp hair be inaccessible, an equivalent quantity of body hair can be utilized. In discussing head hair, we specifically mean scalp hair. Body hair comprises all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result comprises four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning covers the initial integration of a sample into a lab's system. This phase verifies that the sample was sealed and transported correctly, allocates a unique LAN (Laboratory Accessioning Number), and fulfills any supplementary data requirements not addressed by an electronic chain of custody system.
Screening entails an initial rapid assessment for illicit drugs. Screening offers a budget-friendly means to exclude drug use from most samples, however, a positive result must be authenticated for legal purposes. Samples indicating a presumptive positive in Screening necessitate a secondary verification.
Should Screening suggest a presumptive positive, additional hair is taken from the original sample and readied for Extraction. Here, drugs are isolated from hair at significantly lower levels than in other techniques (e.g., urine or oral fluid), contributing to hair drug screening being the most intricate approach to execute.
Verification of any positive screening outcome is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo cleansing prior to confirmation when required. The entire laboratory journey from Accessioning to Confirmation undergoes evaluation under both the CAP (College of American Pathologists) Hair standards and the ISO / IEC 17025 accreditations.
