Hair testing is regarded as an effective means to identify drug and alcohol usage. Hair encapsulates a prolonged history of substance use by capturing biomarkers within the strands as they grow. When collected near the scalp, hair can offer approximately a 3-month detection period for drugs and alcohol. It is straightforward to gather, challenging to tamper with, and convenient to transport.
A 1.5-inch segment of roughly 200 hair strands, akin to a #2 pencil in size, closest to the scalp, is sufficient for obtaining 100mg of hair, which is optimal for screening and confirmation. For EtG, additional tests, or more than 10-panel tests, 150mg of the sample is suggested. We advise measuring the sample on a jeweler’s scale. If scalp hair isn't available, a comparable amount of body hair can be used. "Head hair" refers exclusively to scalp hair, while "body hair" encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test involves four essential steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial sample processing into the lab’s system. This step includes ensuring the sample was sealed and shipped correctly, assigning a random LAN (Laboratory Accessioning Number), and entering any additional data not covered by an electronic chain of custody system.
Screening involves a preliminary review for potential drug abuse. While Screening is a cost-effective method for excluding drug use in most samples, a positive screen requires confirmation to be legally valid. Any samples with positive presumptive results in Screening need further confirmation.
If a sample tests positive in the Screening phase, additional hair is extracted from the original sample for Extraction. This phase involves extracting drugs from hair at a remarkably low concentration, unlike in other methodologies (such as urine or oral fluid), making hair drug screening particularly challenging to perform.
Confirmation of any positive screen result is done using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptively positive samples are cleansed before confirmation as necessary. The full laboratory process, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.
Advantages of hair drug testing:
Limitations:
Note: Despite being commonly termed "hair follicle tests", the test examines the hair strand itself and not the hair follicle beneath the scalp.
