The analysis of hair has emerged as an effective method for identifying drug and alcohol consumption. Hair captures long-term data of alcohol and other drug intake by embedding biomarkers within the hair fibers as they grow. When clipped near the scalp, hair offers an approximate 3-month window for detecting alcohol and drugs. Hair collection is straightforward, hard to tamper with, and simple to transport.
A 1.5-inch piece comprising roughly 200 hair strands (comparable to a #2 pencil's thickness) near the scalp yields 100mg of hair, which is optimal for screening and validation. For EtG, additional tests, and/or more than 10 panels, a 150mg sample is advised. We suggest measuring the hair sample with a jeweler’s scale. If scalp hair is absent, a similar quantity of body hair may be obtained. When mentioning head hair, it exclusively refers to scalp hair. Body hair includes all other varieties (facial, underarm, etc.).
Process Overview
The primary phases in the lab assessment of a drug test are Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the primary handling of a sample within a laboratory's system. This involves confirming that the sample was properly sealed and dispatched, assigning a unique LAN (Laboratory Accessioning Number), and entering any additional data not covered by an electronic chain of custody protocol.
Screening is a preliminary rapid assessment for the presence of drugs. While Screening efficiently excludes drug usage for many samples, a positive outcome requires confirmation for legal validity. Any samples with a provisional positive result in Screening need further verification.
When a sample is assumed positive in the Screening phase, extra hair is extracted from the original sample and prepped for Extraction. During this phase, drugs are isolated from hair at much lower concentrations than in other testing methods (e.g., urine or oral fluid), making hair drug screening the most complex methodology to execute.
Validation of positive screening results is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples showing presumptive positives are cleansed before confirmation as necessary. The complete lab operation from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair label and the ISO / IEC 17025 standards accreditation.
