Hair testing is recognized as a robust method for identifying drug and alcohol consumption. Hair maintains an extended record of alcohol and other drugs by capturing biomarkers within the fibers of the growing hair shaft. When collected near the scalp, hair can offer up to a roughly 3-month detection period for alcohol and other substances. Hair is straightforward to gather, challenging to tamper with, and simple to mail.
A sample measuring 1.5 inches made up of around 200 hair strands (comparable to the width of a #2 pencil) closest to the scalp will provide 100mg of hair, which is the optimal sample for testing and validation. For EtG, supplemental tests, and/or tests exceeding 10 panels, 150mg of the sample is advised. It is suggested to weigh the sample on a jeweler’s scale. If scalp hair is not accessible, an equivalent portion of body hair can be acquired. When mentioning head hair, it pertains exclusively to scalp hair. Body hair includes all other hair varieties (e.g., facial, axillary).
Process Overview
The primary four stages involved in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial handling of a sample into a laboratory’s process. This process includes ensuring that the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry not supplied by an electronic chain of custody system.
Screening consists of an initial rapid evaluation for drugs of abuse. While Screening is an economical method to eliminate drug usage on most samples, a positive screen needs validation to be considered permissible in court. Any samples that show a preliminary positive result in Screening do necessitate a subsequent confirmation.
If a sample registers a preliminary positive result in the Screening phase, additional hair is extracted from the initial sample and prepared for Extraction. In this phase, drugs are extracted from hair at significantly lower concentrations than in alternative methodologies (such as urine or oral fluid), which is why hair drug screening is the most complex method to execute.
Verification of any positive screening result is accomplished via GC/MS, GC/MS/MS, or LC/MS/MS. All samples that show a preliminary positive result are cleansed before verification as required. The entire laboratory process from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
