Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair records a comprehensive history of these substances by embedding biomarkers within the hair strand’s fibers as it grows. When samples are taken close to the scalp, hair can present a detection period for drugs and alcohol reaching up to nearly three months. Collecting hair is straightforward, hard to tamper with, and easy to transport.
A sample measuring 1.5 inches long, consisting of roughly 200 hair strands (similar to the thickness of a #2 pencil), located nearest the scalp, yields 100mg of hair, the preferred amount for both screening and confirmation. If performing EtG tests, additional tests, and/or tests exceeding a 10-panel configuration, then 150mg from the sample is advised. Using a jeweler's scale is recommended for weighing the specimen. If scalp hair cannot be procured, an equivalent quantity of body hair is an acceptable alternative. When we mention head hair, we specifically mean scalp hair. Body hair includes all other types such as facial and axillary hair.
Process Overview
The main procedures involved in lab processing for a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial registration of a sample into a lab’s system. This step includes ensuring that a sample was properly sealed and delivered, generating a random LAN (Laboratory Accessioning Number), and entering any remaining data not covered by an automated chain of custody record.
Screening is a preliminary check for drugs of abuse. While Screening is an economical way to exclude drug use from most samples, confirming positive results is necessary for legal validity. Any samples with a presumptive positive result from Screening require confirmation.
If a sample tests presumptive positive in the Screening phase, additional hair is taken from the original sample and set up for the Extraction phase. In Extraction, drugs are removed from hair at a much lower concentration compared to other methods (such as urine or saliva), making hair drug screening more challenging to perform.
The Confirmation of any positive result from Screening is done using GC/MS, GC/MS/MS, or LC/MS/MS. All samples testing presumptive positive are cleaned before confirmation whenever necessary. From Accessioning to Confirmation, the complete lab procedure is inspected under both CAP (College of American Pathologists) Hair certification and ISO / IEC 17025 accreditation standards.
