Hair analysis is now regarded as a formidable method for identifying drug and alcohol consumption. Hair captures long-term substance use history by embedding biomarkers within the strands of hair as it grows. By acquiring hair near the scalp, one can obtain up to a 3-month period of detection for alcohol and other substances. The collection is straightforward, somewhat resistant to tampering, and convenient for mailing.
A sample measuring 1.5 inches with around 200 strands (approximately the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, the preferred quantity for examination and verification. For EtG, supplementary tests, and those exceeding 10 panels, 150mg is suggested. It's advisable to measure the hair using a jeweler’s scale. Should scalp hair be missing, a comparable quantity of body hair may be gathered. When discussing head hair, we specifically mean scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The crucial phases for processing a sample in the laboratory include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary step where a sample is entered into the lab system. This step verifies if the sample was sealed and sent correctly, assigns a unique LAN (Laboratory Accessioning Number), and finalizes additional data entry that isn't covered by an electronic chain of custody.
Screening is a preliminary assessment for substances of abuse. Although Screening efficiently rules out drug use in most samples, a positive finding necessitates validation for legal acceptance. Samples with tentative positive results during Screening need further confirmation.
In cases where Screening indicates tentative positivity, additional hair is taken from the initial collection for Extraction. In this stage, substances are extracted from hair at significantly lower concentrations than other methods like urine or oral fluid, making hair analysis one of the more complex techniques.
Any positive findings from the screening are verified using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before Confirmation as needed. The whole lab process, from Accessioning through Confirmation, is inspected under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
