Hair analysis has gained recognition as an effective method for identifying the consumption of drugs and alcohol. Hair serves as a detailed record of alcohol and drug usage by encapsulating biomarkers within the fibers of the growing hair shaft. When obtained close to the scalp, hair can offer a detection period of up to 3 months for alcohol and other substances. Hair sampling is straightforward, relatively tamper-proof, and effortlessly transportable.
A 1.5-inch section of approximately 200 hair strands akin to a #2 pencil in thickness, closest to the scalp, yields 100mg of hair—the optimal quantity for screening and verification. For EtG, supplementary tests, and/or panels above 10, a specimen of 150mg is advised. We suggest weighing the sample using a jeweler’s scale. If scalp hair is unavailable, a similar amount of body hair can be collected. In reference to head hair, we mean scalp hair exclusively, while body hair encompasses all other types such as facial or axillary hair.
Process Overview
The key stages involved in the laboratory handling of a drug test sample are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary phase where a sample is entered into a lab’s system. This includes confirming that the sample was sealed and dispatched correctly, allocating a random LAN (Laboratory Accessioning Number), and completing any extra data entry not available from an electronic chain of custody system.
Screening performs an initial rapid assessment for illicit substances. While Screening is an economical approach to exclude drug use in most samples, a positive screen must be verified for legal admissibility. Any samples with a presumptive positive result in Screening necessitate subsequent confirmation.
Should a sample test positive in the Screening phase, additional hair is taken from the initial sample and readied for Extraction. Here, drugs are isolated from hair at a much lower concentration than alternative methods (e.g., urine or oral fluid), highlighting why hair drug testing is the most intricate methodology to execute.
Confirmation of any positive screen is conducted via GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with presumptive positive screens are cleansed as necessary before confirmation. The full lab procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair accreditation and ISO / IEC 17025 standards.
