Hair analysis has emerged as an effective approach for identifying drug and alcohol consumption. The hair traps biomarkers in its fibers, offering a long-term record of substance use. When taken near the scalp, it can show traces of alcohol and drugs for about 90 days. Hair collection is straightforward, challenging to tamper with, and easy to send.
A 1.5-inch segment of roughly 200 hair fibers (around the width of a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal quantity for assessing and confirming results. For EtG, additional tests, or panels exceeding 10, a sample of 150mg is advisable. It is suggested to measure the sample using a jeweler’s scale. If head hair is unavailable, an equivalent amount of body hair can be used. References to head hair pertain solely to scalp hair, while body hair encompasses all other types (e.g., facial, axillary).
Process Overview
The laboratory assessment of a drug test result entails four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the sample's initial entry into the laboratory system. This stage includes confirming proper sealing and shipping of the sample, assigning a random Laboratory Accessioning Number (LAN), and completing any extra data entry absent from an electronic chain of custody system.
Screening involves a preliminary evaluation for substances of abuse. Despite Screening being an economical means to exclude drug use in the majority of cases, a positive screen necessitates confirmation for court acceptance. Samples that are presumptively positive in Screening require further confirmation.
Should a sample yield a presumptive positive result in Screening, more hair is extracted from the original sample for the Extraction phase. Here, substances are extracted from hair at much lower concentrations than in other methods (e.g., urine or oral fluid), illustrating why hair drug screening poses the greatest challenge.
Confirmation of any positive result from screening is achieved via techniques such as GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation whenever needed. The comprehensive lab process, from Accessioning to Confirmation, is assessed under the CAP (College of American Pathologists) Hair classification and accredited to the ISO / IEC 17025 standards.

Note: Despite often being called "hair follicle tests", the test evaluates the hair strand and not the follicle beneath the scalp.
