The examination of hair has gained recognition as an effective method for identifying drug and alcohol consumption. Hair captures biomarkers within the fibers of the developing strand, providing a comprehensive timeline of substance use. When hair is obtained near the scalp, it can offer a detection period of up to roughly 3 months for alcohol and drugs. Collecting hair is straightforward, challenging to contaminate, and convenient to transport.
A sample consisting of 1.5 inches of approximately 200 hair strands (similar in size to a #2 pencil) nearest to the scalp provides 100mg of hair, ideal for tests and confirmations. For add-ons like EtG or tests exceeding 10 panels, a recommendation of 150mg is advised. Using a jeweler’s scale for precise measurement is suggested. In the absence of scalp hair, an equivalent portion of body hair can be used. References to head hair imply scalp hair only, while body hair encompasses other types (facial, axillary, etc.).
Process Overview
Four primary steps are central to the lab processing of drug test results: Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial integration of a sample into a lab’s system. This step verifies the sample's proper sealing and shipment, assigns a random LAN (Laboratory Accessioning Number), and completes any missing data entry not covered by an electronic custody system.
Screening provides a preliminary survey for substance misuse. It offers a cost-effective approach to eliminate drug presence in most samples. However, any positive screening must be confirmed to withstand legal scrutiny. Presumptively positive samples from Screening necessitate follow-up confirmation.
When a sample shows a presumptive positive in Screening, additional hair is extracted from the original sample and prepared for Extraction. In this phase, drugs are isolated from hair at significantly lower concentrations compared to other tests (e.g., urine or oral fluid), which makes hair drug screening exceptionally challenging.
Positive screening confirmations are conducted using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo a washing process before confirmation when required. The entire laboratory sequence, from Accessioning to Confirmation, is subject to review under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
