Hair testing is now recognized as an effective instrument for identifying drug and alcohol consumption. Hair offers a long-term history of alcohol and other substances by embedding biomarkers within the fibers of the evolving hair strand. When taken near the scalp, hair can reveal up to roughly a 90-day detection span for alcohol and other substances. The collection of hair is straightforward, somewhat resistant to tampering, and easy to transport.
A 1.5-inch segment of roughly 200 hair strands (about the size of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal amount for screening and validation. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of the sample is suggested. It is advisable to weigh the specimen using a jeweler’s scale. If scalp hair is missing, a similar amount of body hair can be gathered. When speaking of head hair, we mean scalp hair exclusively. Body hair pertains to all other hair categories (facial, axillary, etc.).
Process Overview
The four critical steps in the lab processing of a drug test report are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is about initially processing a sample into a lab’s system. This process includes checking that the sample was sealed and dispatched correctly, assigning an arbitrary LAN (Laboratory Accessioning Number), and fulfilling any other data entry not supplied by an electronic chain of custody system.
Screening offers the first quick review for drugs of abuse. While Screening is a budget-friendly method to dismiss drug use in most samples, a positive screen needs to be confirmed for legal admissibility. Samples that are preliminarily positive in Screening must undergo secondary confirmation.
Should a sample appear positive during the Screening phase, more hair is taken from the initial specimen and set up for Extraction. In this phase, drugs are separated from hair at a much lower concentration than in other techniques (e.g., urine or oral fluid), highlighting why hair drug screening is the most challenging technique to conduct.
Any positive Screening outcomes undergo Confirmation via GC/MS, GC/MS/MS or LC/MS/MS. All preliminarily positive samples are washed before confirmation as required. From Accessioning to Confirmation, the entire lab process is analyzed under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
