Hair analysis is recognized as a significant method for identifying alcohol and drug use. Strands of hair capture biomarkers within their fibers, offering a lengthy historical record of substance use. By collecting hair near the scalp, one can achieve a detection period of approximately three months for alcohol and drugs. Hair is easy to gather, moderately resistant to tampering, and straightforward to transport.
An optimal 1.5-inch hair sample, consisting of around 200 strands (roughly the thickness of a #2 pencil) from near the scalp, will yield 100mg, ideal for both initial screening and subsequent confirmation. For tests including EtG, additional panels, or those exceeding 10, a sample weight of 150mg is advisable. Using a jeweler’s scale is suggested for measuring the specimen. If scalp hair collection is not feasible, an equivalent volume of body hair can be used. "Head hair" refers specifically to scalp hair, while "body hair" denotes other types, such as facial or axillary hair.
Process Overview
The drug test processing sequence in the laboratory involves four critical steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample undergoes initial processing into the laboratory’s system. This step verifies proper sealing and shipment, assigns the sample a random Laboratory Accessioning Number (LAN), and completes any outstanding data entry not addressed by an electronic chain of custody.
Screening serves as an initial assessment for abuse substances. While cost-effective in eliminating the likelihood of drug usage in most samples, any positives detected in Screening require confirmation for legal admissibility. Samples testing presumptively positive in Screening demand further confirmation.
If the Screening stage indicates a positive result, additional hair is extracted from the original sample for use in Extraction. This phase involves retrieving drugs from the hair at a far lower concentration than that used in other testing methods, such as urine or oral fluid, making hair drug screening the most challenging methodology.
Any positive results from Screening undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS techniques. Necessity dictates that presumptive positive samples be washed before confirmation. The entire process, from Accessioning to Confirmation, adheres to both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
