Hair testing has emerged as a potent means for the recognition of substance and alcohol consumption. Hair signifies an enduring timeline of alcohol and drugs by encapsulating biomarkers within the fibers of the hair as it grows. When gathered near the scalp, hair can offer an approximate 3-month observation period for alcohol and drugs. Hair is straightforward to gather, relatively challenging to tamper with, and simple to transport.
A 1.5-inch segment containing around 200 hair strands (roughly the size of a #2 pencil) nearest to the scalp will produce 100mg of hair, which is the optimal sample for both analysis and confirmation. For EtG, additional tests, or screenings exceeding 10 panels, 150mg of the sample is advised. Using a jeweler's scale is recommended for weighing the specimen. If scalp hair is absent, a comparable amount of body hair may be harvested. When mentioning head hair, it pertains solely to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The process within the lab for determining a drug test result entails four paramount stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary processing of a sample into the lab's system. This procedure includes confirming that the sample was sealed and dispatched accurately, allocating a random LAN (Laboratory Accessioning Number), and finishing any supplementary data entry not accommodated by an electronic chain of custody system.
Screening involves an initial cursory assessment for illicit drugs. Though Screening is an economical method to negate drug use in most samples, a positive result must be substantiated to hold up legally. Any samples that emerge presumptively positive during Screening demand a secondary verification.
If a sample tests presumptively positive during the Screening phase, more hair is extracted from the original specimen and readied for Extraction. This phase involves isolating drugs from hair at a significantly reduced concentration compared to other techniques (e.g., urine or oral fluid), reason being why hair drug screening stands as the most challenging technique to execute.
Confirmation of any positive screening outcome is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as needed. The complete laboratory procedure from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair classification and the compliance to ISO / IEC 17025 standards.

Note: Even though often labeled as "hair follicle tests", the analysis actually examines the hair strand, not the follicle below the scalp.
