Hair testing is recognized as an effective method for identifying drug and alcohol consumption. This process utilizes hair, which captures biomarkers of alcohol and drugs within the fibers of the growing strand, giving a historical record of use. When hair is collected near the scalp, it can reveal drug and alcohol use for up to roughly a 3-month period. The collection of hair is straightforward, it is rather hard to tamper with, and it is convenient to transport.
A hair specimen of 1.5 inches, comprising around 200 strands (comparable to the thickness of a #2 pencil) positioned closest to the scalp, yields 100mg, which is the optimal amount for preliminary testing and verification. For EtG tests, additional screenings, or tests exceeding 10 panels, 150mg of hair is advisable. Using a jeweler’s scale to weigh the sample is suggested. If scalp hair cannot be obtained, a corresponding quantity of body hair could be used. When addressing head hair, it specifically pertains to scalp hair. In contrast, body hair denotes all other types such as facial and axillary hair.
Process Summary
Drug test processing in the lab is divided into four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the sample’s preliminary processing within a lab’s database. This phase verifies if the sample was sealed securely and shipped correctly, assigns a random Laboratory Accessioning Number (LAN), and completes any outstanding data input that an electronic chain of custody system might not supply.
Screening is a rapid assessment for drug presence. While it is a budget-friendly method to exclude drug presence in many samples, a positive outcome in Screening must be verified for legal admissibility. Samples that test positive presumptively in Screening require further validation through a secondary confirmation.
If a sample indicates a presumptive positive at the Screening phase, extra hair from the initial sample is collected for the Extraction phase. Here, drugs are isolated from hair at significantly lower concentrations compared to other methods like urine or oral fluid analysis, making hair drug screening notably challenging to conduct.
The Confirmation phase for any positive screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples undergo washing before confirmation as needed. The complete laboratory procedure, from Accessioning to Confirmation, is assessed in accordance with CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
