Hair testing has emerged as a compelling method for identifying drug and alcohol consumption. Hair strands capture biomarkers within their fibers as they grow, providing a long-lasting record of substance use. When collected near the scalp, hair can reveal alcohol and drug use for up to about three months. Hair is straightforward to collect, relatively resistant to tampering, and convenient to transport.
A 1.5-inch segment comprising roughly 200 hair strands (about the diameter of a #2 pencil) taken from the scalp provides 100mg of hair, the optimal sample for analysis and validation. For EtG, additional tests, and/or panels exceeding 10, a 150mg specimen is advised. It is suggested to measure the sample with a jeweler’s scale. In the absence of scalp hair, an equivalent quantity of body hair can be used. By head hair, we mean scalp hair specifically, whereas body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary processing of a sample into the lab's system. This step includes checking that the sample was properly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and filling in any extra data entry missing from an electronic chain of custody system.
Screening is a preliminary swift inspection for drug presence. Although Screening is a budget-friendly approach to eliminate drug use for most samples, a positive result requires confirmation to be valid in legal proceedings. Samples that indicate positivity during Screening need a follow-up confirmation.
If a sample appears positive during Screening, additional hair is extracted from the original specimen for Extraction. In this phase, drugs are extracted from the hair at significantly lower concentrations than in other methods (e.g., urine or oral fluid), making hair drug screening one of the most challenging methods to execute.
Confirming a positive screening result is done using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples indicating preliminary positivity are cleansed before confirmation, as necessary. The entire lab procedure, from Accessioning to Confirmation, is reviewed under both the CAP (College of American Pathologists) Hair category and ISO/IEC 17025 accreditation standards.
