Hair testing has increasingly become recognized as a robust method for identifying drug and alcohol consumption. By capturing biomarkers within the fibers of the growing hair strand, hair reveals a long-term usage history of alcohol and drugs. If gathered near the scalp, hair can offer up to a roughly 3-month window for detecting alcohol and drugs. Hair collection is straightforward, relatively resistant to tampering, and simple to transport.
A 1.5-inch segment of about 200 hair strands (approximately the diameter of a #2 pencil) nearest to the scalp equates to 100mg of hair, which is the optimal sample for analysis and confirmation. For EtG, additional tests, and/or those exceeding 10 panels, 150mg of hair is advisable. It is suggested to weigh the sample using a jeweler’s scale. Should scalp hair be unavailable, a similar quantity of body hair may be collected. When speaking of head hair, it specifically means scalp hair. Body hair encompasses all other types (such as facial, axillary, etc.).
Process Overview
The laboratory process of a drug test result encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.
In Accessioning, the initial sample is processed within a lab’s system. This step involves confirming that the sample was sealed and transported correctly, assigning an arbitrary LAN (Laboratory Accessioning Number), and finishing any remaining data entry not covered by an electronic chain of custody system.
Screening consists of a preliminary check for drugs of abuse. Though Screening is an economical approach to eliminate drug use for most samples, a positive screen necessitates confirmation for court admissibility. Samples that are presumptively positive during Screening require a subsequent confirmation.
Should a sample yield a presumptive positive in Screening, additional hair is drawn from the original specimen for Extraction. This phase involves extracting drugs from hair at significantly lower concentrations than in other methods like urine or oral fluid, which is why hair drug screening is among the most challenging methodologies.
Confirmation of any positive screen result is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples are washed as necessary. The entire laboratory procedure from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
