The use of hair testing has emerged as an effective method for detecting drug and alcohol consumption. Hair captures a prolonged history of alcohol and drug use by embedding biomarkers within its growing fibers. When collected at the scalp, hair can offer a detection duration of up to roughly 90 days for alcohol and other drugs. The collection of hair is straightforward, challenging to tamper with, and simple to transport.
A specimen of 1.5 inches consisting of roughly 200 hair strands (approximately the size of a #2 pencil) nearest to the scalp provides 100mg of hair, which is the perfect sample for screening and confirmatory purposes. For EtG, add-ons, or tests beyond 10 panels, 150mg of hair is suggested. Using a jeweler’s scale for weighing the sample is advised. If scalp hair isn't available, a comparable quantity of body hair may be used. "Head hair" pertains to only scalp hair. "Body hair" includes all other hair types (facial, axillary, etc.).
Process Overview
The key phases of the laboratory process for a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial steps of processing the sample in a lab's system. This involves checking that the sample was appropriately sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and completing any extra data entry not covered by an electronic chain of custody system.
Screening serves as an initial, rapid scan for drugs of abuse. While Screening is a cost-efficient method to exclude drug use in most samples, a positive screen requires confirmation to be legally admissible. Any samples showing a presumptive positive in Screening need further confirmation.
If a sample is identified as presumptive positive at the Screening phase, additional hair is taken from the initial sample for Extraction. Here, drugs are extracted from hair at a lower concentration compared to other methods (e.g., urine or oral fluid), making hair drug testing the most complex method to conduct.
Positive screening results undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are washed before confirmation when necessary. The complete laboratory process, from Accessioning to Confirmation, is evaluated under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.
