Hair analysis has emerged as an effective method for identifying the use of drugs and alcohol. The hair offers an extended timeline of usage by encapsulating biomarkers within the growing hair shaft. When taken near the scalp, hair can reveal consumption from up to a quarter-year for alcohol and illicit substances. It is easy to collect hair, challenging to tamper with it, and convenient to send it for testing.
A hair sample measuring 1.5 inches, consisting of roughly 200 strands (approximately the diameter of a #2 pencil), yields 100mg of hair, which is optimal for screening and confirmation. For E.g., addon tests, beyond the ten-panel screenings, 150mg of sample is advisable. We suggest weighing the sample using a jeweler’s scale. In the absence of scalp hair, an equivalent amount of body hair can be substituted. "Head hair" refers exclusively to scalp hair, while "body hair" encompasses all other types, including facial and axillary hair.
Process Overview
The key phases in the lab analysis of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample undergoes initial processing into a lab's system. This involves ensuring the sample’s seal and proper shipment, assigning a random Laboratory Accessioning Number (LAN), and inputting supplementary data not captured by an e-chain of custody system.
Screening entails a preliminary, rapid assessment for substance abuse. Despite being a cost-efficient means of dismissing drug usage in most samples, a positive outcome from Screening necessitates confirmation for legal admissibility. Presumptive positives from Screening must undergo secondary confirmation.
If Screening results indicate a presumptive positive, further hair is extracted from the original specimen for the Extraction process. Here, substances are isolated from hair at lower concentrations compared to other methods (e.g., urine or saliva), thus making hair testing one of the most complex methodologies.
Confirmation of positive screening is achieved through GC/MS, GC/MS/MS, or LC/MS/MS techniques. Before confirmation, all presumptive positives undergo washing as needed. The end-to-end lab process from Accessioning to Confirmation is subject to review under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
