The analysis of hair is recognized as an effective method for uncovering drug and alcohol consumption. Hair acts as a chronic ledger, capturing biomarkers within the strands’ structure. When collected near the scalp, it offers a detection span of up to about 90 days for alcohol and substances. Hair is easy to gather, not easily tampered with, and simple to transport.
A 1.5-inch lock with roughly 200 hairs (around the thickness of a #2 pencil) near the scalp will yield 100mg of hair, the preferred sample size for testing. For EtG, add-ons, or panels exceeding 10, a 150mg sample is advised. It is suggested to weigh the sample on a jeweler's scale. If scalp hair isn’t available, equivalent body hair can be used. Head hair specifically refers to scalp hair, while body hair includes all other types (like facial, axillary, and similar).
Process Overview
The laboratory processing of drug test outcomes includes the steps of Accessioning, Screening, Extraction, and Confirmation.
Accessioning is about initially processing a sample into a lab’s system. This step ensures the sample's seal and shipment integrity, assigns a LAN (Laboratory Accessioning Number) at random, and completes any extra data input not covered by an electronic custody chain.
Screening provides a rapid assessment for drug presence. Though cost-effective for dismissing drug use in most samples, a positive screen requires confirmation to be court-valid. Samples with presumptive positives in Screening need secondary confirmation.
If Screening indicates a presumptive positive, additional hair is taken from the initial sample for Extraction. In this phase, substances are removed from hair at lower concentrations than other methods (such as urine or oral fluid), thus making hair drug screening a challenging methodology.
Positive screenings are confirmed through GC/MS, GC/MS/MS, or LC/MS/MS. Presumed positives undergo necessary washing before confirmation. The full lab process from Accessioning to Confirmation adheres to both CAP (College of American Pathologists) Hair standards and accreditation per ISO / IEC 17025 standards.
