Hair testing is recognized as an effective method for detecting drug and alcohol consumption. Hair archives a long-term record of alcohol and drug use by capturing biomarkers within its fibers as it grows. When hair is taken close to the scalp, it can offer up to a 3-month detection period for alcohol and other drugs. Hair sampling is easy to collect, tough to tamper with, and convenient to transport.
A sample of 1.5 inches, comprising around 200 hair strands (equivalent to a #2 pencil's thickness) nearest to the scalp, will yield 100mg, the optimal amount for both screening and confirmation processes. For EtG, additional testing, and/or assays over 10 panels, 150mg is advised. It's advisable to weigh the sample using a jeweler's scale. Should scalp hair be unavailable, similar amounts of body hair can be gathered. By head hair, we exclusively mean scalp hair. Body hair encompasses all other hair forms (such as facial and axillary hair).
Process Overview
The key phases in lab processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Within Accessioning, a sample is initially processed into the lab’s system. Tasks entail checking that the sample was correctly sealed and transported, assigning it a random LAN (Laboratory Accessioning Number), and performing any extra data entry when not supplied by an electronic chain of custody system.
Screening carries out a swift primary check for drug abuse. While Screening is economical in excluding drug use in most samples, a positive screening must be confirmed for legal admissibility. Any samples tentatively positive in Screening necessitate secondary confirmation.
If the Screening phase results in a presumptive positive, additional hair is extracted from the initial sample and prepared for Extraction. Here, drugs are drawn out of hair at significantly lower concentrations compared to other techniques (e.g., urine or oral fluid), rendering hair drug screening the most challenging technique to perform.
Positive screening outcomes require Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo a washing step before confirmation as necessary. The holistic lab process from Accessioning through Confirmation is assessed under CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 standard accreditation.
