Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair captures a long-term record of alcohol and drug use by embedding biomarkers in the growing hair fibers. When harvested near the scalp, hair offers up to roughly a 3-month window for detecting drugs and alcohol. Hair is easy to gather, relatively tamper-proof, and simple to transport.
A 1.5-inch segment containing around 200 hair strands (about the diameter of a #2 pencil) nearest to the scalp yields 100mg, which is the perfect amount for both screening and confirmation procedures. For EtG, additional tests, and/or assessments exceeding 10 panels, a 150mg sample is suggested. We advise using a jeweler’s scale to weigh the sample. If scalp hair is lacking, an equivalent portion of body hair can be used. Concerning head hair, we mean scalp hair exclusively. Body hair indicates all other hair types (facial, axillary, etc.).
Process Overview
The laboratory analysis of a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial handling of a sample into a lab’s system. This process includes checking that the sample was sealed and sent correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry not managed by an electronic chain of custody system.
Screening involves an initial swift evaluation for abusive drugs. While Screening serves as a cost-effective method to rule out drug use in most samples, a positive screen must be verified to be acceptable in legal contexts. Any samples that show a presumptive positive during Screening necessitate a subsequent confirmation.
If a sample is presumptive positive during the Screening phase, further hair is taken from the original sample and readied for Extraction. In this phase, drugs are retrieved from hair at a considerably lower concentration than in other methods (ex. urine or oral fluid), which is why hair drug testing is the hardest method to conduct.
Verification of any positive screening outcome is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation if needed. The comprehensive lab procedure from Accessioning to Confirmation is inspected under both the CAP (College of American Pathologists) Hair classification and the accreditation to ISO / IEC 17025 standards.
