Hair testing is now recognized as an effective means of identifying drug and alcohol use. Hair captures biomarkers in the strands as they grow, offering a considerable timeline of alcohol and drug consumption. When samples are taken near the scalp, hair can offer detection capabilities for alcohol and drugs over a span of up to roughly three months. Hair collection is straightforward, hard to tamper with, and simple to transport.
A sample measuring 1.5 inches consisting of roughly 200 hairs (approximately the size of a #2 pencil) nearest to the scalp yields 100mg of hair, representing the optimal quantity for both screening and confirmation. For EtG, additional analyses, and/or panels exceeding 10, a specimen size of 150mg is suggested. It's advisable to measure the specimen using a jeweler’s scale. If scalp hair cannot be obtained, an equivalent quantity of body hair can be used. By head hair, we specifically mean scalp hair. Body hair encompasses other hair types (facial, axillary, etc.).
Process Overview
The four key stages in the laboratory analysis of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into a lab's system. This process includes ensuring the sample was properly sealed and dispatched, generating a random LAN (Laboratory Accessioning Number), and finalizing any additional data entry not supplied by an electronic chain of custody system.
Screening offers an initial, swift examination for drugs of abuse. Though Screening is an economical method to exclude drug use in most samples, a positive result must be confirmed for legal admissibility. Samples presumed positive in Screening necessitate secondary confirmation.
Should a sample be presumptively positive at the Screening phase, additional hair is extracted from the initial sample and made ready for Extraction. Drugs are drawn from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), making hair drug screening particularly challenging to perform.
Positive screening results undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are cleansed before confirmation as necessary. The complete laboratory procedure, from Accessioning to Confirmation, is audited according to the CAP (College of American Pathologists) Hair designation and compliance with the ISO / IEC 17025 standards.
