Hair analysis is acknowledged as a dynamic approach for identifying drug and alcohol consumption. It offers a prolonged history of substance use by capturing biomarkers within the hair shaft as it grows. When gathered near the scalp, hair can extend up to a three-month window for detecting alcohol and other substances. Hair sampling is easy to perform, fairly challenging to tamper with, and straightforward to mail.
A sample measuring 1.5 inches of about 200 hair strands (approximately equivalent to a #2 pencil) nearest to the scalp provides 100mg of hair, the preferred quantity for testing and verification. For EtG, additional testing, and/or panels exceeding ten, 150mg of the sample is advised. It's a good idea to measure the sample using a jeweler’s scale. If scalp hair is not accessible, an equivalent portion of body hair may be used. When we mention head hair, we specifically mean scalp hair. Body hair encompasses all other hair types (such as facial, axillary, etc.).
Process Overview
The laboratory procedures for determining a drug test outcome include four fundamental steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step of integrating a sample into a lab’s database. It involves checking that the sample has been properly sealed and transported, assigning it a random LAN (Laboratory Accessioning Number), and completing any supplemental data entry absent in an electronic chain of custody setup.
Screening offers a swift preliminary assessment for substance abuse. Though Screening cost-effectively excludes drug usage in most samples, a positive result necessitates confirmation for court admissibility. Samples that appear presumptively positive during Screening will need follow-up confirmation.
Should a sample appear presumptively positive in Screening, further hair is extracted from the initial sample for Extraction. This stage involves removing drugs from hair at significantly lower concentrations than other techniques (e.g., urine or oral fluid), positioning hair drug screening as a more complex method to execute.
Confirmation of any positive Screening outcome is accomplished through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo a wash before confirmation, as needed. The end-to-end laboratory protocol from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation.
