Hair analysis is increasingly regarded as an effective method for identifying drug and alcohol consumption. Hair captures a long-term record of alcohol and other drugs by enclosing biomarkers within the hair strand's fibers as it grows. When cut near the scalp, hair offers an approximate 3-month window for detecting alcohol and other drugs. Hair collection is straightforward, relatively challenging to tamper with, and easy to send.
A 1.5-inch portion of around 200 hair strands (similar to a #2 pencil in size) closest to the scalp yields 100mg of hair, the preferred sample size for both screening and confirmation. For EtG, additional tests, and/or tests exceeding 10 panels, a 150mg sample is advisable. It's best to weigh the sample with a jeweler’s scale. If scalp hair is unavailable, an equivalent amount of body hair can be collected. When mentioning head hair, we're specifically referring to scalp hair alone. Body hair pertains to all other types of hair (facial, axillary, etc.).
Process Overview
The four key stages in laboratory processing of a drug test are Accessioning, Screening, Extraction, and Confirmation.
Accessioning starts with the initial processing of a sample into the laboratory's system. This procedure includes verifying the sample's seal and shipment, assigning a random LAN (Laboratory Accessioning Number), and fulfilling any further data entry not covered by an electronic chain of custody system.
Screening involves an initial rapid assessment for substances of abuse. Though Screening is an economical approach to exclude drug usage in most samples, a positive screen requires confirmation to be permissible in legal proceedings. Any samples that show presumptive positives in Screening necessitate a follow-up confirmation.
In cases where a sample shows a presumptive positive during the Screening phase, additional hair is extracted from the initial sample and prepped for Extraction. During this stage, drugs are derived from hair at significantly lower concentrations than with other techniques (like urine or oral fluid), which is why hair drug screening is the most intricate method to execute.
Confirmation of any positive screening result is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before Confirmation as needed. The entire lab process, from Accessioning to Confirmation, is reviewed under both the CAP (College of American Pathologists) Hair specification and the accreditation to ISO / IEC 17025 standards.

Note: Though often termed "hair follicle tests", the test actually examines the hair strand, not the follicle beneath the scalp.
