Hair analysis has emerged as an effective means for identifying drug and alcohol usage. Hair stores a comprehensive record of alcohol and other substances by embedding biomarkers within the strands. When gathered near the scalp, hair can reveal substance use for up to about three months. Hair is easy to collect, challenging to tamper with, and straightforward to transport.
A 1.5-inch portion consisting of around 200 hair strands (similar in size to a #2 pencil) nearest the scalp will provide 100mg, which is the optimal quantity for initial testing and verification. For EtG, additional screenings, and tests exceeding 10 panels, 150mg of the sample is advised. It's recommended to measure the sample using a jeweler’s scale. If head hair is not an option, an equivalent volume of body hair can be used. When we mention head hair, we specifically mean hair from the scalp. Body hair indicates any other hair types including facial, axillary, etc.
Process Overview
The lab processing of a drug test involves four key phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary phase of processing a sample within a lab’s system. This step includes ensuring the sample was appropriately sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any additional required data entry that an electronic chain of custody may not cover.
Screening is a swift initial evaluation for potential drug usage. Although Screening offers a cost-effective way to exclude drug usage for most samples, any positive screen must be validated to hold up in legal settings. Samples that test positive during Screening require further confirmation.
Should a sample test positive in the Screening phase, additional hair is drawn from the initial sample and readied for Extraction. During this phase, substances are extracted from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), making hair drug testing particularly complex to perform.
Confirmation of any positive results obtained during Screening is achieved through GC/MS, GC/MS/MS or LC/MS/MS. All samples showing presumptive positivity undergo a wash before confirmation if necessary. The entire laboratory process, from Accessioning to Confirmation, is conducted in accordance with both the CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 accreditation standards.
