Hair evaluations are increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair acts as a long-standing record of substance use by embedding biomarkers within the strands of growing hair. When obtained close to the scalp, hair can offer a detection timeframe of up to roughly three months for alcohol and other substances. Hair collection is straightforward, somewhat resistant to tampering, and convenient for transport.
A sample of 1.5 inches with around 200 hairs (comparable to the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, suitable for analysis and verification. For more comprehensive tests such as EtG, additional panels, or panels exceeding ten, 150mg of the sample is suggested. It is advisable to use a jeweler’s scale for weighing the specimen. If scalp hair isn’t present, a similar quantity of body hair can be used. The term 'head hair' refers solely to scalp hair, whereas 'body hair' encompasses all other categories (facial, axillary, etc.).
Process Overview
The laboratory processing of drug test outcomes involves four primary phases: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample is initially integrated into the lab’s system. This step includes ensuring the sample was sealed and sent correctly, assigning a unique LAN (Laboratory Accessioning Number), and completing any extra data processing absent in an electronic chain of custody system.
Screening consists of an initial rapid assessment for substance abuse. Screening is a budget-friendly means to exclude drug presence in most samples; however, a positive screen must be validated to be court-admissible. Any samples with a tentative positive result in Screening require additional confirmation.
In cases of tentative positivity in the Screening phase, additional hair is extracted from the original sample and readied for Extraction. This phase involves deriving drugs from hair at a significantly lower concentration than in other methods (e.g., urine or oral fluid), which is why hair drug screening is considered the most intricate methodology to execute.
Confirmation of any positive Screening result is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive undergo necessary washing before confirmation. The comprehensive laboratory procedure, from Accessioning to Confirmation, adheres to both the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.
