Hair analysis is regarded as an effective means for identifying drug and alcohol consumption. Hair records long-term usage by embedding biomarkers within its fibers as it grows. Collected near the scalp, hair can indicate alcohol and drug usage over a span of around 3 months. Hair is easily collected, hard to tamper with, and simple to transport.
A sample measuring 1.5 inches, comprising roughly 200 hairs (about a #2 pencil's thickness) nearest to the scalp, yields 100mg, an optimal sample for testing and verification. For assessments like EtG, add-ons, and testing exceeding 10 panels, a 150mg sample is advisable. It is best to measure the sample on a jeweler's scale. Absent scalp hair, a similar amount of body hair is suitable. Reference to head hair pertains solely to scalp hair. Body hair includes all other types (facial, axillary, etc.).
Process Overview
The key stages in the lab examination of a drug test include Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the sample's initial integration into the lab system. This phase checks the proper sealing and shipment of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes any lacking data entry not covered by an electronic chain of custody procedure.
Screening offers a preliminary drug check. While cost-effective for ruling out drug use in most samples, a positive result in Screening necessitates confirmation for legal validity. Samples presumed positive must undergo further confirmation.
For samples presumptively positive at the Screening phase, more hair is extracted from the initial sample for Extraction. Here, drugs are isolated from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug analysis.
Confirmation of any positive screen results is done through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positives are washed before confirmation if needed. The entire lab process is audited under CAP (College of American Pathologists) Hair designation and accredited by ISO / IEC 17025 standards.
