Hair analysis is now recognized as an effective method for detecting the use of drugs and alcohol. Hair strands capture biomarkers within their fibers, offering a prolonged timeline of substance use insights. When collected adjacent to the scalp, hair can reveal alcohol and drug usage history for up to three months. Hair collection is straightforward, somewhat resistant to tampering, and convenient for transport.
A 1.5-inch length of around 200 hairs (similar to a #2 pencil in width) near the scalp provides 100mg, which is the optimal sample size for both screening and confirmation. For EtG tests, add-ons, or panels above 10, 150mg is suggested. It's advisable to measure the specimen using a jeweler's scale. If scalp hair is unavailable, an equivalent volume of body hair is acceptable. "Head hair" refers specifically to scalp hair; "body hair" includes all other types (facial, axillary, etc.).
Process Overview
The laboratory workflow for drug testing encompasses four key steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample is logged into the lab’s system. This step ensures the sample's proper sealing and shipment, assigns a random Laboratory Accessioning Number (LAN), and includes any necessary manual data entry missing from an electronic chain of custody.
Screening is a preliminary analysis for substances of abuse. Though cost-effective, any positive screenings must undergo confirmation to be court-admissible. Presumptive positive screens require follow-up confirmation.
Samples flagged as presumptive positives during Screening have additional hair drawn from the initial sample for Extraction. At this stage, drugs are isolated from hair at a lower concentration than other mediums (e.g., urine, oral fluid), posing greater methodological challenges.
To confirm any positive screenings, techniques like GC/MS, GC/MS/MS, or LC/MS/MS are employed. Presumptive positives are cleansed as required before confirmation. The lab process from Accessioning through Confirmation aligns with both the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.
