Hair analysis is increasingly recognized as a vital method for identifying drug and alcohol consumption. Hair captures enduring evidence of substances by embedding biomarkers within the strands. When obtained near the scalp, hair offers a detection period of up to three months for drugs and alcohol. It is easy to collect, challenging to falsify, and straightforward to transport.
A 1.5-inch section consisting of approximately 200 hair strands (resembling the diameter of a #2 pencil) near the scalp will yield 100mg, the preferred amount for analysis and confirmation. For EtG, additional tests, or panels exceeding 10, 150mg is suggested. Using a jeweler’s scale to measure the specimen is advisable. If scalp hair isn’t accessible, an equivalent volume of body hair can be gathered. Head hair refers specifically to scalp hair. Body hair encompasses all other hair categories (facial, axillary, etc.).
Process Overview
The four key phases in processing a drug test in a lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the sample's preliminary intake into the lab system. This procedure verifies that the sample is securely sealed and mailed, assigns a random LAN (Laboratory Accessioning Number), and completes any leftover data entry not captured by an electronic chain of custody system.
Screening is an initial review for substances of abuse. While Screening is an economical way to eliminate drug presence in most samples, a confirmed screen is necessary for courtroom acceptance. Samples with presumptive positives in Screening need another level of confirmation.
If Screening suggests a positive result, more hair is used from the original sample for Extraction. In this phase, substances are extracted from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), which is why hair drug analysis is one of the most complex methods to execute.
Positive results in Screening are verified through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleaned before confirmation as required. The entire lab process from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair designation and also under ISO / IEC 17025 accreditation.
