Hair analysis has emerged as an effective method for determining drug and alcohol consumption. Hair retains a lasting record of alcohol and drug use by encapsulating biomarkers in the fibers of the growing hair strand. When cut near the scalp, hair can show evidence of alcohol and other drugs for up to around 3 months. Hair is straightforward to collect, relatively hard to tamper with, and simple to transport.
A 1.5-inch segment of about 200 hair strands (similar in size to a #2 pencil) nearest to the scalp equates to 100mg of hair, which is the preferred sample amount for both screening and confirmation. For EtG, add-ons, or for tests beyond 10 panels, 150mg of hair is suggested. We advise using a jeweler’s scale to measure the specimen. If scalp hair is not available, an equivalent amount of body hair may be taken. When referring to head hair, it specifically means scalp hair. Body hair includes all other types such as facial and axillary hair.
Process Overview
The four primary steps in laboratory processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the first stage of incorporating a sample into a laboratory's framework. This entails confirming that the sample was properly sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and concluding any supplementary data entry not provided by an electronic chain of custody system.
Screening may include an initial check for potential drug usage. While Screening is an economical approach for eliminating drug use on the majority of specimens, a positive screen result must be verified to be valid in legal proceedings. Any samples that yield a preliminary positive in Screening necessitate follow-up confirmation.
If a sample shows a preliminary positive during Screening, additional hair is drawn from the original specimen for Extraction. At this phase, drugs are isolated from hair at concentrations much lower than in other test methodologies (e.g., urine or oral fluid), which makes hair drug screening an especially challenging testing method.
Confirmation of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with leads indicating positivity are cleansed before confirmation if needed. The entire laboratory workflow from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and adherence to ISO / IEC 17025 standards.
