Hair examinations have emerged as a significant method for identifying drug and alcohol consumption. Hair captures a long-term narrative of alcohol and various drugs by embedding biomarkers within the fibers of the hair as it grows. When clipped close to the scalp, hair can offer nearly a 3-month timeframe for detecting alcohol and drug presence. Hair is straightforward to gather, relatively challenging to manipulate, and uncomplicated to transport.
A sample of 1.5 inches consisting of about 200 hairs (similar to the thickness of a #2 pencil) near the scalp will yield 100mg of hair, which is the optimal sample for testing and validation. For EtG, specialized tests, and panels exceeding 10, 150mg of hair is advised. It is suggested to use a jeweler's scale for weighing the specimen. If scalp hair isn't an option, a similar quantity of body hair can be taken. Note that when referring to head hair, it specifically means scalp hair only. Body hair includes all other types (facial, underarm, etc.).
Process Overview
Accessioning, Screening, Extraction, and Confirmation are the four major stages in processing a drug test result in the laboratory.
Accessioning is the first step in introducing a sample into the laboratory's workflow. This involves ensuring that the sample was correctly sealed and transported, assigning it an arbitrary LAN (Laboratory Accessioning Number), and completing any extra data entry not covered by an electronic chain of custody mechanism.
Screening is a preliminary swift assessment for substances of abuse. Though Screening is a cost-efficient approach to eliminate drug presence in the bulk of samples, a positive finding necessitates validation to be court admissible. Samples showing presumptive positivity in Screening must undergo further confirmation.
Should a sample appear presumptive positive in Screening, additional hair is extracted from the initial sample for the Extraction phase. In this phase, drugs are isolated from hair at markedly lower concentrations than other methods (e.g., urine or saliva), attributing to hair drug screening being the most intricate method to execute.
The Confirmation of any positive screening outcome is executed through GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples are cleansed as required. The full laboratory procedure from Accessioning to Confirmation is scrutinized under CAP (College of American Pathologists) Hair stipulations and the accreditation per ISO / IEC 17025 criteria.
