Hair analysis is now recognized as a robust method for uncovering drug and alcohol consumption. By embedding biomarkers within the strands of growing hair, this method offers an extended timeline of substance usage. Collected near the scalp, hair offers a detection window extending roughly up to 90 days for substances. The collection process is straightforward, tough to tamper with, and convenient for transport.
A 1.5-inch hair sample, around 200 strands akin to the thickness of a #2 pencil close to the scalp, yields 100mg, which is ideal for both screening and confirmation steps. For EtG, specialized tests, and/or screenings exceeding 10-panel coverage, 150mg of the sample is advised. Use a jeweler's scale for specimen weighing. If head hair isn’t available, similar amounts of body hair can be collected. Here, head hair specifically pertains to scalp hair, while body hair encompasses all other varieties (facial, axillary, etc.).
Process Overview
The laboratory processing for drug test results encompasses four pivotal stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of initially integrating a sample into the lab’s system. This step involves ensuring the sample was properly sealed and shipped, allocating a unique LAN (Laboratory Accessioning Number), and fulfilling any extra data entry absent from an electronic chain of custody format.
Screening is a preliminary assessment for drugs of abuse. Although it is a cost-effective procedure to eliminate drug use suspicions for most samples, a positive screening must undergo confirmation to hold in legal circumstances. Samples yielding a presumptive positive in Screening necessitate an additional confirmation step.
If a sample demonstrates a presumptive positive during Screening, additional hair is retrieved from the original sample and readied for Extraction. Here, drugs are isolated from the hair at much lower concentrations than seen with alternate approaches (like urine or oral fluid), which is why hair drug testing is notably challenging compared to other methodologies.
Using GC/MS, GC/MS/MS or LC/MS/MS methodologies, the Confirmation process validates any positive screening results. Presumptive positive samples undergo necessary washing before confirmation. This entire laboratory sequence from Accessioning to Confirmation is rigorously reviewed under both CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.
