Hair analysis has become recognized as an effective means for detecting drug and alcohol consumption. The strands of hair capture biomarkers by embedding them in their growing fibers, providing an extended history of alcohol and other drugs. A sample taken near the scalp offers a detection timeframe of up to about 90 days for alcohol and other drugs. Hair collection is straightforward, not easy to tamper with, and simple to transport.
A collection of 1.5 inches in length, consisting of approximately 200 strands (the diameter of a standard #2 pencil) closest to the scalp, yields 100mg, which is the ideal quantity for both screening and confirmation. For EtG, additional testing, and/or panels exceeding 10, 150mg of the sample is advisable. Using a jeweler’s scale is suggested for measuring the specimen. In the absence of scalp hair, the same amount of body hair can be gathered. The term head hair refers specifically to scalp hair. Body hair encompasses all other hair varieties (facial, axillary, etc.).
Process Overview
The key steps in the laboratory process for delivering a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial introduction of a sample into the laboratory system. This step entails confirming that the sample was securely sealed and transported correctly, allocating a unique LAN (Laboratory Accessioning Number), and performing any supplemental data entry that an electronic chain of custody system might not cover.
Screening is a preliminary rapid assessment for detecting drug use. Although Screening is a budget-friendly approach for excluding drug use in most samples, any positive results during screening need to be verified before being admissible in a legal setting. Samples identified as presumptively positive in Screening require subsequent confirmation.
If a sample indicates a presumptive positive in Screening, additional hair is retrieved from the initial sample for the Extraction phase. It is during Extraction that drugs are removed from hair at notably lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug testing one of the most challenging methodologies.
Confirmation of any screening positives is conducted using GC/MS, GC/MS/MS or LC/MS/MS techniques. All samples that are presumptively positive are washed before confirmation when necessary. The complete laboratory procedure from Accessioning to Confirmation is assessed in compliance with the CAP (College of American Pathologists) Hair specifications and based on ISO / IEC 17025 accreditations.
