Hair testing is recognized as an effective method for identifying drug and alcohol consumption. Hair offers an extended history of substance use by embedding biomarkers in the fibers of the hair as it grows. A sample taken close to the scalp can reveal substance use for up to three months. The collection process is straightforward, it's relatively tough to tamper with, and shipment is uncomplicated.
A 1.5-inch cluster of roughly 200 hairs (comparable to the thickness of a #2 pencil) taken from nearest to the scalp yields approximately 100mg, which is ideal for both screening and confirmation tests. For EtG, additional screenings, and/or beyond 10-panel testing, it's suggested to collect 150mg. It's advisable to use a jeweler’s scale for weighing the specimen. If scalp hair isn't an option, an equivalent volume of body hair is acceptable. "Head hair" specifically refers to scalp hair, whereas "body hair" encompasses all other types (such as facial and axillary hair).
Process Overview
The laboratory processing of drug tests includes Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial integration of a specimen into the lab's system. This phase ensures the sample was correctly sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and supplements any missing data not provided by an electronic chain of custody system.
Screening involves a preliminary quick check for substance abuse. It's a cost-efficient means to exclude drug use for most samples, though any positive findings in the screening stage require confirmation for legal admissibility. Samples flagged as presumptively positive necessitate further confirmation.
When a sample is flagged positive during Screening, more of the hair from the original sample is utilized for Extraction. This stage involves extracting drugs from hair, which occurs at significantly lower concentrations compared to urine or oral fluid testing, making hair drug screening one of the most challenging procedures to conduct.
Confirmation of positive screening outcomes is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All samples deemed presumptively positive are washed if necessary before confirmation. The full laboratory procedure from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair designation and meets the ISO / IEC 17025 standards.
