Hair testing has emerged as an effective means to detect substance and alcohol consumption. Hair captures long-term records of alcohol and different substances by embedding biomarkers in the strands of growing hair. When clipped near the scalp, hair can offer a detection timeframe of up to roughly 90 days for alcohol and other substances. Hair's collection is straightforward, somewhat resistant to tampering, and convenient for transport.
A 1.5-inch segment of about 200 hair strands (around the dimension of a #2 pencil) closest to the scalp yields 100mg of hair, which is the optimal sample amount for both screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, a sample of 150mg is advised. We recommend using a jeweler’s scale to weigh the sample. If scalp hair cannot be obtained, a similar amount of body hair may be used. When we talk about head hair, we specifically mean scalp hair. Body hair includes all other hair forms (such as facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result encompasses four main steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the preliminary processing of a sample within a laboratory's system. This step ensures the sample was correctly sealed and dispatched, assigns an arbitrary LAN (Laboratory Accessioning Number), and completes any additional data entry absent from an electronic chain of custody system.
Screening performs an initial assessment for substance abuse. Although Screening is a cost-efficient method to eliminate drug consumption in most samples, a positive result from the screen must be confirmed to be valid in legal proceedings. All samples showing a potentially positive result in Screening necessitate further confirmation.
Should a sample be considered potentially positive during the Screening phase, further hair is drawn from the original specimen and prepped for Extraction. This phase involves extracting drugs from hair at a considerably lower concentration than in other methods (e.g., urine or oral fluid), thus hair drug screening is among the most challenging methodologies.
Positive screening results undergo Confirmation using methods like GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing as required before confirmation. The entire lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair classification and compliance with ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: While often termed "hair follicle tests", the analysis evaluates the hair strand, not the follicle beneath the scalp.
