Hair analysis has evolved into a robust method for uncovering drug and alcohol consumption. Hair retains a comprehensive timeline of alcohol and drug intake by embedding markers within the hair as it grows. When clipped near the scalp, hair can offer roughly a 90-day detection period for drug and alcohol presence. Hair is easy to collect, tougher to tamper with, and straightforward to transport.
A sample of about 200 strands, measuring 1.5 inches (around the size of a #2 pencil), close to the scalp yields about 100mg of hair, the perfect quantity for initial testing and confirmation. For EtG, additional tests, and/or panels exceeding 10, a specimen of 150mg is suggested. It is advisable to use a jeweler's scale to measure the sample's weight. If scalp hair is not an option, a comparable amount of body hair can be utilized. When discussing head hair, it pertains solely to scalp hair. Body hair encompasses all other hair varieties (facial, axillary, etc.).
Process Overview
The laboratory handling of a drug test result comprises four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step where a sample is introduced into the lab's system. This phase ensures that the sample was sealed and dispatched correctly, assigns a unique LAN (Laboratory Accessioning Number), and finalizes any leftover data input absent from an electronic chain of custody protocol.
Screening serves as an initial rapid assessment for substance abuse. Though Screening efficiently excludes drug use in most cases, to be valid in court, a positive result requires confirmation. Samples presumed positive in Screening must receive additional validation.
Should a sample indicate a presumptive positive at the Screening stage, additional hair is extracted from the original sample to undergo Extraction. During Extraction, substances are drawn from hair at concentrations significantly lower than those found in other methods (e.g., urine or oral fluid), making hair drug screening one of the most challenging methods to execute.
Confirmation of a positive Screening outcome employs GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples that are presumptively positive are cleansed before confirmation if need be. The entire lab sequence, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair criteria and the compliance with ISO / IEC 17025 standards.

Note: The term "hair follicle tests" is often mentioned, though the analysis targets the hair strand, not the follicle beneath the scalp.
