Hair testing has gained recognition as an effective method for identifying drug and alcohol usage. Hair captures long-term evidence of alcohol and drugs by securing biomarkers within the growing hair strand fibers. When taken close to the scalp, hair can offer roughly a 3-month period for drug and alcohol detection. Hair is easy to collect, challenging to tamper with, and simple to transport.
A sample size of 1.5 inches consisting of around 200 hairs (approximately the width of a #2 pencil) closest to the scalp will yield 100mg of hair, which is the preferred amount for both screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, a sample of 150mg is advisable. It's suggested to measure the sample on a jeweler’s scale. In cases where scalp hair isn't available, a comparable amount of body hair can be gathered. When we mention head hair, we mean scalp hair exclusively. Body hair pertains to all other hair varieties (facial, axillary, etc.).
Process Overview
The four key stages in the laboratory processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the preliminary processing of a sample into a lab’s system. This step ensures the sample was sealed and sent correctly, assigns a random LAN (Laboratory Accessioning Number), and completes any extra data input not covered by an electronic chain of custody system.
Screening involves an initial rapid assessment for drugs of abuse. While Screening is a cost-effective method to exclude drug use in most samples, a positive screen must be verified for court acceptability. Samples that test positive in Screening require a further confirmation stage.
If a specimen shows presumptive positivity during Screening, additional hair is extracted from the original sample and prepared for Extraction. This stage extracts drugs from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), making hair drug screening a challenging methodology.
Confirmation of any positive screening outcome is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before confirmation as necessary. The full lab process from Accessioning to Confirmation is thoroughly reviewed under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
