Through time, hair testing has emerged as a robust method for identifying drug and alcohol consumption. Hair acts as a historical archive for alcohol and other drugs, capturing indicators in the fibers of its growing strands. When collected near the scalp, hair can offer a detection period of up to around 3 months for alcohol and various drugs. It's easy to collect, somewhat resistant to tampering, and straightforward to ship.
A collection of about 200 strands, measuring 1.5 inches and resembling the size of a #2 pencil, closest to the scalp provides 100mg of hair, which is optimal for screening and confirmation. For EtG, additional screening, and/or tests exceeding 10 panels, 150mg of the sample is advised. Using a jeweler’s scale for weighing the specimen is recommended. If scalp hair is unavailable, an equivalent amount of body hair may be used. "Head hair" refers exclusively to scalp hair. "Body hair" includes all other types (facial, axillary, etc.).
Process Overview
The standardized steps in laboratory processing of a drug test result consist of Accessioning, Screening, Extraction, and Confirmation.
In Accessioning, the sample undergoes its initial laboratory system processing. It includes checking that the sample was properly sealed and shipped, assigning it a random LAN (Laboratory Accessioning Number), and completing any data entry gaps not covered by an electronic chain of custody system.
Screening conducts an initial rapid test for drugs of abuse. Though Screening serves as an economical approach to exclude drug use for most samples, a positive screen requires confirmation for court admissibility. Samples with presumptive positives need secondary confirmation.
In cases where a sample tests presumptively positive during the Screening phase, additional hair is extracted from the original sample for Extraction. Here, drug extraction occurs at much lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening the most challenging method to execute.
Confirmation follows any positive Screening result, employing GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleansed before necessary confirmation. The entire process from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair accreditation and the ISO / IEC 17025 standards.
