Hair testing is increasingly recognized as an effective means for detecting drug and alcohol consumption. It captures a long-term history of substances by embedding biomarkers within the hair strand's evolving fibers. When taken close to the scalp, the hair may offer up to a 3-month timeframe for identifying alcohol and drugs. It is easy to collect, somewhat resistant to tampering, and straightforward to transport.
A sample of 1.5 inches, comprising around 200 hair strands (akin to a #2 pencil size) nearest to the scalp, yields 100mg of hair, which is optimal for both screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, a 150mg portion is preferred. It is advisable to weigh the sample using a jeweler’s scale. If scalp hair is unavailable, a similar quantity of body hair can be collected. By head hair, we mean scalp hair exclusively. Body hair encompasses all other types (such as facial or axillary hair).
Process Overview
The laboratory process of a drug test result consists of four principal phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning relates to incorporating a sample into a laboratory's system initially. It involves checking that the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and performing any extra data entry not covered by an electronic chain of custody system.
Screening is a preliminary rapid evaluation for drugs of abuse. Although Screening serves as a cost-efficient method to eliminate drug use in most samples, a positive screen needs confirmation for court admissibility. Any samples that are presumptively positive in Screening require a secondary confirmation.
If a sample shows a presumptive positive in the Screening phase, additional hair is extracted from the initial sample and readied for Extraction. In this phase, substances are isolated from hair at much lower concentrations than in other approaches (such as urine or oral fluid), which is why hair drug testing is the most challenging methodology to execute.
Confirmation of any positive screening outcome is conducted via GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptive positive samples are cleaned before confirmation as necessary. The entire laboratory process from Accessioning to Confirmation is evaluated under the CAP (College of American Pathologists) Hair designation and accredited according to ISO / IEC 17025 standards.
