Hair testing is recognized as a highly effective method for detecting drug and alcohol consumption. Hair strands capture long-term drug and alcohol indications by embedding biomarkers within the hair fibers as they grow. Collected near the scalp, hair can offer up to a three-month detection timeframe for substances. This method of collection is straightforward, difficult to tamper with, and convenient to transport.
A 1.5-inch section consisting of approximately 200 hair strands (akin to the thickness of a #2 pencil) nearest the scalp will yield 100mg of hair, the optimal quantity for both screening and verification purposes. For tests like EtG, additions, and/or those exceeding 10 panels, a 150mg sample is advisable. Using a jeweler’s scale to weigh the specimen is recommended. Where scalp hair is not present, an equivalent measure of body hair can be used. Head hair references only scalp hair, whereas body hair includes all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result encompasses four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the primary processing of a sample within a laboratory system. It involves ensuring the sample is properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing supplementary data entries absent from an electronic chain of custody system.
Screening entails a preliminary, rapid evaluation for drug abuse. Although cost-effective for negating drug usage in most samples, a positive screen mandates confirmation to be legally valid. Samples with presumptive positivity in Screening require secondary validation.
For specimens showing potential positivity during Screening, additional hair is extracted from the initial sample for the Extraction process. This phase involves isolating drugs from hair at lower concentrations than in other methods (e.g., urine or oral fluid), rendering hair drug screening the most complex methodology.
Positive screening outcomes are confirmed through techniques like GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation as necessary. From Accessioning to Confirmation, the full laboratory process adheres to CAP (College of American Pathologists) Hair designation and is accredited to ISO / IEC 17025 standards.

Note: Commonly termed as "hair follicle tests", this assessment evaluates the hair strand rather than the follicle beneath the scalp.
