Hair testing is regarded as a potent method to identify drug and alcohol consumption. By trapping biomarkers in the fibers of the growing hair strand, hair offers a prolonged history of alcohol and other drug usage. When obtained close to the scalp, hair can present up to an estimated 3-month detection period for alcohol and other substances. Hair collection is straightforward, relatively resistant to tampering, and convenient to transport.
A 1.5-inch sample containing approximately 200 hair strands (around the thickness of a #2 pencil) nearest to the scalp provides 100mg of hair, which is the optimal quantity for initial and confirmatory tests. For EtG, additional tests, and/or more than 10-panel tests, a 150mg specimen is suggested. We suggest weighing the sample with a jeweler’s scale. If scalp hair is absent, a similar volume of body hair can be gathered. When mentioning head hair, we specifically mean scalp hair. Body hair includes all other hair types (facial, axillary, etc.).
Process Overview
The four primary steps in the laboratory processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial handling of a sample into a lab’s system. This phase includes ensuring that the sample was correctly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry missing from an electronic chain of custody system.
Screening consists of an initial rapid check for drugs of abuse. Although Screening is a cost-efficient method to exclude drug use in most samples, a positive screen must be confirmed to be valid in court. Any samples that show a presumptive positive in Screening require an additional confirmation.
If a sample is presumptively positive during the Screening phase, additional hair is extracted from the initial specimen for Extraction. At this stage, drugs are extracted from hair at a considerably lower concentration than in other methods (e.g., urine or oral fluid), which makes hair drug screening the most challenging method to conduct.
Confirmation of any positive screening outcome is completed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleaned before confirmation as necessary. The entire laboratory procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and adherence to ISO / IEC 17025 standards.
