Hair testing has emerged as an effective instrument for uncovering drug and alcohol consumption. The fibers in a growing hair strand trap biomarkers, offering a long-term history of substances like alcohol. Hair collected close to the scalp can reveal alcohol and drug use over roughly a 3-month period. It's easy to collect, relatively tough to tamper with, and simple to transport.
A sample measuring 1.5 inches, comprising about 200 hair strands (roughly the diameter of a #2 pencil) taken closest to the scalp, will yield 100mg of hair, which is the ideal sample size for both screening and confirmation. For tests such as EtG, add-ons, or those exceeding 10 panels, a 150mg sample is advisable. Using a jeweler’s scale to weigh the specimen is recommended. If scalp hair isn't available, an equivalent amount of body hair can be collected. Here, head hair specifies scalp hair, while body hair refers to other hair types (like facial or axillary).
Process Overview
The laboratory processing of a drug test comprises four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial stage where a sample enters a laboratory’s system. This step includes checking that the sample was sealed and dispatched correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any data entry not covered by an electronic chain of custody system.
Screening is a preliminary check for drugs of abuse. Though it's a cost-effective means to identify drug usage in most samples, a positive screen needs further confirmation to be court-admissible. Samples testing presumptively positive require a secondary confirmation.
In cases where a sample tests positive in Screening, more hair is extracted from the initial sample and prepared for Extraction. This phase involves removing drugs from the hair at concentrations much lower than other methods (such as urine or oral fluid), pointing to why hair drug screening is more challenging to conduct.
Confirmation of a positive screening result utilizes GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples undergo washing as necessary before confirmation. The entire laboratory journey from Accessioning to Confirmation undergoes scrutiny under both the CAP (College of American Pathologists) Hair designation and the accreditation adhering to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Commonly called "hair follicle tests", these tests analyze the hair strand and not the follicle beneath the scalp.
