Hair evaluations are increasingly regarded as an effective means for identifying drug and alcohol consumption. Hair captures a prolonged record of alcohol and drugs by embedding biomarkers within the strands of developing hair. When taken near the scalp, hair can offer up to a three-month detection timeframe for alcohol and other substances. Hair collection is straightforward, relatively hard to tamper with, and easy to transport.
A 1.5-inch segment of roughly 200 hair strands (around the width of a #2 pencil) nearest to the scalp yields 100mg of hair, which is an optimal sample for both screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of the sample is advisable. It's suggested to measure the specimen using a jeweler’s scale. If scalp hair is absent, an equivalent quantity of body hair can be used. When addressing head hair, it particularly refers to scalp hair. Body hair encompasses all other varieties of hair (facial, axillary, etc.).
Process Overview
The laboratory procedure to render a drug test result consists of four core steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the preliminary handling of a specimen within the laboratory framework. This step ensures the sample was properly sealed and dispatched, assigns a unique LAN (Laboratory Accessioning Number), and completes any other necessary data entry absent from an electronic chain of custody system.
The Screening phase is a preliminary, quick assessment to check for drug abuse. Though Screening is an economical approach to dismiss drug use in most samples, any positive finding must be confirmed for legal admissibility. Samples flagged as presumptively positive in Screening necessitate secondary verification.
Should a specimen be flagged as potentially positive during Screening, additional hair from the initial sample is utilized for Extraction. In this process, drugs are isolated from hair at lower concentrations than in alternate methods (e.g., urine or oral fluid), making hair drug testing the most challenging approach.
Verification of any positive Screening outcome is handled through GC/MS, GC/MS/MS or LC/MS/MS. Presumptive positive samples are cleansed prior to required confirmation. From Accessioning to Confirmation, the entire laboratory process is scrutinized per the CAP (College of American Pathologists) Hair classification and certified to ISO / IEC 17025 criteria.

Note: Though often termed "hair follicle tests", the analysis focuses on the hair strand itself and not the follicle beneath the scalp.
