Hair testing is increasingly recognized as an effective means for identifying drug and alcohol usage. Hair captures a comprehensive history of substance consumption, preserving markers within the fibers of the developing hair strand. If taken from near the scalp, hair may offer approximately a 3-month observation span for alcohol and drug detection. Hair collection is straightforward, hard to tamper with, and easy to transport.
A sample of around 1.5 inches consisting of approximately 200 hair strands (roughly the thickness of a #2 pencil) nearest to the scalp provides 100mg of hair, which is the optimal sample size for both screening and confirmation. For EtG, additional tests, and/or screenings exceeding 10 panels, a 150mg sample is advised. Utilizing a jeweler’s scale is recommended for weighing the specimen. In cases where scalp hair cannot be collected, an equivalent quantity of body hair may be used. When mentioning head hair, we specify scalp hair only. Body hair encompasses all other types of hair (facial, underarm, etc.).
Process Overview
The four fundamental stages in the lab processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step of processing a sample into the lab’s system. This involves ensuring that the sample was properly sealed and dispatched, assigning a unique LAN (Laboratory Accessioning Number), and completing any supplementary data entry not covered by an electronic chain of custody system.
Screening is a preliminary quick assessment for substance abuse. Although Screening is an economical method to rule out drug consumption on most samples, a positive screen must be verified to be acceptable as evidence in court. All samples with a preliminary positive Screen result require further confirmation.
When a sample shows a preliminary positive in the Screening phase, more hair is extracted from the original specimen and readied for Extraction. This step involves extracting drugs from hair at a significantly lower concentration than other methods (e.g., urine or saliva), making hair drug screening the most challenging method to conduct.
Confirmation of any positive screening result is performed utilizing GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples that tested presumptively positive undergo washing before confirmation if necessary. The comprehensive lab process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair classification and compliance with the ISO / IEC 17025 standards.
