The perception of hair testing has evolved as an effective method for identifying drug and alcohol use. Hair captures a long-term record of alcohol and drugs by embedding biomarkers within the fibers of the hair strand as it grows. When taken close to the scalp, hair can reveal up to about a 90-day detection period for alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and convenient to transport.
A 1.5-inch segment of approximately 200 hair strands (roughly the thickness of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the perfect sample for examination and confirmation. For EtG, add-ons, and/or assays exceeding 10 panels, 150mg of the specimen is advised. It's recommended to measure the specimen with a jeweler’s scale. If scalp hair is unobtainable, an equivalent amount of body hair can be gathered. When talking about head hair, we mean only scalp hair. Body hair includes all other hair varieties (facial, axillary, etc.).
Process Overview
The four key stages in the lab processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step of processing a sample into a lab's system. This includes confirming the sample was sealed and transported correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any remaining data input not covered by an electronic chain of custody system.
Screening entails an initial rapid evaluation for substance abuse. While Screening is an economical method to eliminate drug use in the majority of samples, a positive screen must be verified to be valid in court. Any samples deemed presumptively positive in Screening necessitate a secondary confirmation.
If a sample shows presumptive positivity in the Screening phase, additional hair is extracted from the initial specimen and made ready for Extraction. In this phase, drugs are isolated from hair at a much lower concentration than in other techniques (e.g., urine or oral fluid), making hair drug screening one of the most challenging methodologies to execute.
Confirmation of any positive screen result is done through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed prior to confirmation if necessary. The full laboratory process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.
