Hair analysis has gained recognition as a compelling method for identifying drug and alcohol consumption. Hair strands offer an extended historical record of alcohol and drug markers by entrapping them within the strand's fibers. When samples are collected near the scalp, hair can reveal usage markers for up to approximately a 3-month period for both alcohol and drugs. The collection process for hair is straightforward, relatively tamper-resistant, and simple to transport.
A 1.5-inch section comprising around 200 strands (comparable to the diameter of a #2 pencil) taken nearest to the scalp yields 100mg of hair, which constitutes the optimal sample size for both initial screening and subsequent confirmation. For EtG testing, additional panels, and/or tests exceeding 10 panels, a quantity of 150mg is advised. It is suggested that this sample be measured using a jeweler’s scale. In situations where scalp hair is not available, an equivalent quantity of body hair can be used. When head hair is mentioned, it refers solely to scalp hair. Body hair encompasses all other hair types (such as facial and axillary hair).
Process Overview
The laboratory procedure for drug test processing consists of four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into the lab’s system. This process verifies that the sample was correctly sealed and shipped, assigns a unique LAN (Laboratory Accessioning Number), and completes any missing data entry not captured by an electronic chain of custody system.
Screening serves as an initial rapid assessment for substance misuse. Although Screening is a cost-efficient method to exclude drug use in most samples, any positive result must undergo confirmation to be admissible in legal settings. Samples that test presumptively positive during Screening necessitate a secondary verification.
Should a sample yield a presumptive positive in the Screening phase, additional hair from the original sample is used for the Extraction process. Here, drugs are isolated from hair at concentrations significantly lower than other techniques (such as urine or oral fluid tests), which positions hair drug testing as the most complex methodology.
Confirmation for any positive screening outcomes is performed using GC/MS, GC/MS/MS, or LC/MS/MS technologies. All presumptively positive samples undergo washing before confirmation as necessary. The entire process, from Accessioning to Confirmation, adheres to both the CAP (College of American Pathologists) Hair protocol and ISO / IEC 17025 accreditation standards.
