Hair analysis has emerged as a potent method for detecting drug and alcohol consumption. It offers a prolonged history of substance intake by capturing biomarkers within the fibers of the growing hair. When sampled near the scalp, hair can provide a detection window of up to roughly 3 months for substances like alcohol and drugs. Hair is easy to gather, resistant to tampering, and straightforward to transport.
A sample measuring 1.5 inches, consisting of around 200 strands close to the scalp, will yield 100mg of hair, which is the preferred amount for both screening and confirmation. For testing involving EtG, additional elements, or exceeding 10 panels, a quantity of 150mg is suggested. We advise using a jeweler’s scale for weighing the sample. If scalp hair isn’t obtainable, an equivalent amount of body hair can be used. When we refer to head hair, we specifically mean scalp hair. Body hair encompasses all other types (such as facial or axillary hair).
Process Overview
The laboratory processing of a drug test result is divided into four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the preliminary processing of a sample in a lab's system, including verifying the proper packaging and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry not covered by an electronic chain of custody system.
Screening entails a quick initial examination for the presence of drugs. Although Screening is cost-effective for excluding drug use in most samples, a confirmed positive result is necessary for legal admissibility. Samples that test presumptively positive in Screening need secondary verification.
If a sample shows a presumptive positive in the Screening phase, additional hair is collected from the original sample and readied for Extraction. During this phase, drugs are extracted from hair at much lower levels than in other methods, such as urine or oral fluid, making hair drug screening one of the most challenging procedures to execute.
GC/MS, GC/MS/MS, or LC/MS/MS are used for the Confirmation of any positive screening outcome. All samples that are presumptively positive undergo a wash before Confirmation if required. The complete lab procedure from Accessioning to Confirmation adheres to the CAP (College of American Pathologists) Hair guidelines and is accredited to ISO / IEC 17025 criteria.
