Hair analysis is being recognized as an effective means for identifying drug and alcohol consumption. The hair retains a long-term record of alcohol and various drugs by embedding biomarkers within the fibers of the growing hair strand. When cut close to the scalp, hair offers an approximately 3-month detection span for alcohol and substances. Collecting hair is straightforward, modifying it is relatively challenging, and it can be transported without difficulty.
A hair sample of 1.5 inches, consisting of around 200 strands (equal to the thickness of a #2 pencil) nearest to the scalp provides 100mg, which is the preferred amount for testing and validation. For EtG, additional analyses, and/or tests exceeding 10 panels, a specimen of 150mg is suggested. It's advisable to use a jeweler’s scale for weighing the sample. In cases where scalp hair is unavailable, a comparable quantity of body hair can be used. Scalp hair refers solely to head hair, while body hair encompasses all other varieties (facial, axillary, etc.).
Process Overview
The primary stages in laboratory processing for a drug test outcome consist of Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step where the sample is integrated into the laboratory's system. This step includes confirming the sample's proper sealing and shipping, generating a random LAN (Laboratory Accessioning Number), and completing any extra data input absent from an electronic chain of custody system.
Screening is an initial rapid assessment for substance abuse. Although Screening is a cost-effective method to eliminate drug presence in most samples, any positive screening requires confirmation to be accepted in legal settings. Samples deemed presumptively positive during Screening require follow-up confirmation.
If a sample is found to be presumptively positive at the Screening phase, additional hair is extracted from the original sample and prepped for Extraction. In this phase, drugs are isolated from hair at significantly lower concentrations than in other methods (e.g., urine or oral fluid), making hair drug screening the most complex method to conduct.
Confirmation for any positive screening is done using GC/MS, GC/MS/MS, or LC/MS/MS. All samples tentatively positive are washed before confirmation as necessary. The complete lab process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.
