Hair testing has emerged as an influential method for unveiling alcohol and drug consumption. By capturing biomarkers within the hair fiber, it offers an extended history of substance use. When sampled near the scalp, hair can reveal drug and alcohol use for roughly three months. The collection of hair is straightforward, resistant to tampering, and simple to transport.
A 1.5-inch segment consisting of about 200 hair strands (approximately the diameter of a #2 pencil) taken closest to the scalp will yield 100mg—the preferred sample amount for initial screening and confirmation. For EtG, added tests, and/or those exceeding 10 panels, 150mg of the sample is advisable. It is recommended to weigh the sample using a jeweler’s scale. Should scalp hair be inaccessible, an equivalent volume of body hair is suitable. The term head hair specifically relates to scalp hair, whereas body hair encompasses all other types (such as facial or axillary).
Process Overview
The fundamental steps in processing a laboratory drug test result are Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample is initially logged into a lab’s system. This step includes confirming the proper sealing and shipping of the sample, generating a random LAN (Laboratory Accessioning Number), and finishing any extra data input that an electronic chain of custody might miss.
Screening is a preliminary fast assessment to detect drug abuse. Though this step efficiently eliminates drug usage in most samples, a positive outcome must be confirmed for legal validity. Samples that show presumptive positivity in Screening necessitate further confirmation.
If Screening marks a sample as presumptively positive, additional hair is extracted from the original sample to prepare for Extraction. This stage extracts drugs from hair at lower concentrations than alternative methods (like urine or oral fluids), which makes hair drug testing a challenging procedure.
To confirm presumptive positives, methods like GC/MS, GC/MS/MS, or LC/MS/MS are employed. Samples positive in prescreening receive washing prior to Confirmation if necessary. The complete lab procedure from Accessioning to Confirmation is reviewed under the guidelines of the CAP (College of American Pathologists) Hair recognition and ISO / IEC 17025 accreditation.
