Hair testing is regarded as a robust method for discerning drug and alcohol use. Hair can record a lengthy history of substance use by encapsulating biomarkers within the hair strand fibers. When sourced near the scalp, hair offers about a 3-month detection duration for alcohol and other substances. Hair is easy to gather, relatively hard to tamper with, and straightforward to transport.
A 1.5-inch segment of approximately 200 hair strands (roughly the width of a #2 pencil) near the scalp yields 100mg of hair, the preferred sample size for analysis and validation. For EtG, supplementary tests, and/or tests exceeding 10 panels, a 150mg sample is advised. It's recommended to weigh the specimen using a jeweler’s scale. If scalp hair isn't accessible, a comparable quantity of body hair can be collected. 'Head hair' specifically denotes scalp hair, whereas 'body hair' includes all other types (facial, axillary, etc.).
Process Overview
The four principal steps in processing a drug test result in a lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step where a sample is entered into the laboratory’s system. This process ensures the sample was correctly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any extra data entry not covered by an electronic chain of custody.
Screening is a preliminary check for drugs of abuse. While Screening is an economical method to exclude drug use in numerous samples, any positive results require confirmation for court admissibility. Samples that test positive during Screening necessitate a secondary confirmation.
If a sample shows a presumptive positive in Screening, more hair is extracted from the original sample and readied for Extraction. In this phase, drugs are extracted from hair at a notably lower concentration than through other methods (e.g., urine or oral fluid), which is a reason why hair drug testing is among the more challenging methodologies.
Any positive Screening outcomes undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all samples with presumptive positive results are washed as needed. The complete laboratory procedure from Accessioning to Confirmation adheres to the standards of both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.
