Utilizing hair testing is increasingly recognized as a vital method for detecting drug and alcohol consumption. Hair acts as a historical record of substance use by trapping biomarkers within the fibers as hair grows. A sample taken near the scalp can offer a 3-month detection period for substances. Hair collection is straightforward, less prone to tampering, and convenient for shipping.
A sample measuring 1.5 inches with around 200 hair strands (equivalent to a #2 pencil's thickness) taken closest to the scalp is needed to gather 100mg, which is optimal for both screening and confirmation. For tests including EtG, additional panels over 10, 150mg of hair is advised. It is suggested to weigh the sample using a jeweler's scale. If scalp hair is unavailable, body hair in equivalent quantity can be used. When mentioning head hair, it specifies scalp hair alone. Body hair refers to all other types of hair (facial, axillary, etc.).
Process Overview
The principal stages in processing a drug test result in the laboratory include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the primary integration of a specimen into the lab's systems by verifying proper sealing and shipping, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional data input if not already provided via an electronic chain of custody system.
Screening represents an initial assessment to identify drugs of abuse. While Screening is cost-effective to exclude drug use in most samples, further confirmation is required for court admissibility for any positive screen. Samples showing presumptive positives in Screening require additional confirmation.
If a sample indicates a presumptive positive in Screening, additional hair is extracted from the initial specimen for the Extraction stage. During Extraction, substances are retrieved from hair at significantly lower concentrations than other techniques (e.g., urine or oral fluid), making hair drug screening the most challenging to perform.
Confirmed screening results are achieved through GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicating presumptive positives undergo washing before confirmation. The entire lab procedure from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Note: Although sometimes labeled as "hair follicle tests", the procedure analyzes the hair strand and not the follicle beneath the scalp.
