Hair analysis has emerged as an effective method for detecting drug and alcohol consumption. Hair can reveal prolonged histories of substance use by capturing biomarkers within the hair fiber. When cut close to the scalp, hair can offer a detection period spanning up to three months for alcohol and other substances. Hair can be easily gathered, is somewhat resistant to tampering, and is straightforward to transport.
A 1.5-inch segment of roughly 200 hair strands (about the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, which is optimal for screening and confirmation. For EtG, additional tests, and/or more than 10 panels, 150mg of the sample is advisable. We suggest measuring the sample on a jeweler’s scale. If scalp hair cannot be obtained, an equivalent quantity of body hair may be taken. When we say head hair, we are specifically referring to scalp hair. Body hair includes all other types of hair (facial, axillary, etc.).
Process Overview
The four primary phases in the lab processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial intake of a sample into the lab’s system. This comprises ensuring the sample was properly sealed and sent, assigning a unique LAN (Laboratory Accessioning Number), and filling in any additional data entry absent from an electronic chain of custody system.
Screening encompasses a preliminary rapid assessment for drug abuse. While Screening is an economical method to exclude drug usage for most samples, a positive screen must be confirmed for legal admissibility. Any samples that are presumptively positive in Screening require a secondary confirmation.
If a sample is flagged as presumptively positive during the Screening, more hair is extracted from the original specimen and readied for Extraction. Here, drugs are removed from hair at a considerably lower concentration than in other techniques (e.g., urine or oral fluid), which is why hair drug testing poses the greatest challenge.
Confirmation of any positive screening result is carried out via GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptively positive samples are cleansed before confirmation as required. The entire lab workflow from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
