Urine| Hair Follicle | Oral Fluid | Blood | ETG
Hair testing has emerged as an effective method to identify alcohol and drug use. Hair strands capture biomarkers within the fibers, offering an extensive history of substance usage. When sourced near the scalp, hair samples provide an approximate detection period of up to 3 months for both alcohol and drugs. Collecting hair samples is straightforward, relatively hard to tamper with, and convenient for transportation.
A 1.5-inch segment consisting of around 200 hair strands, equivalent to the thickness of a #2 pencil, when taken nearest to the scalp offers 100mg of hair, which is the preferred amount for both preliminary and confirmatory screening. For EtG, additional analyses, and tests exceeding 10 panels, a specimen weighing 150mg is advisable. It's suggested to utilize a jeweler’s scale for specimen measurement. If scalp hair is unavailable, an equivalent quantity of body hair can be collected. The term head hair specifically denotes scalp hair, while body hair encompasses all other hair types (e.g., facial, axillary).
Process Overview
There are four primary stages in the lab processing of drug test outcomes: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial processing of a sample into a laboratory's system. This step involves confirming the sample's proper sealing and shipping, assigning an arbitrary LAN (Laboratory Accessioning Number), and completing any additional data input absent from an electronic chain of custody system.
Screening involves a preliminary rapid check for substances of abuse. Although Screening provides a cost-effective method to dismiss drug usage in most cases, confirming a positive screen is essential for court admissibility. Any samples yielding a presumptively positive result in Screening require a secondary Confirmation.
If a sample screens presumptively positive, additional hair is extracted from the initial specimen for the Extraction stage. Here, drugs are extracted from hair at significantly lower concentrations than those in urine or oral fluid methods, making hair drug tests the most challenging to conduct.
Positive screening results are verified using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples undergo washing as warranted prior to Confirmation. The comprehensive laboratory procedure, from Accessioning to Confirmation, undergoes review under both the CAP (College of American Pathologists) Hair designation and adherence to ISO / IEC 17025 standards.

Note: Despite often being termed "hair follicle tests", these tests analyze the hair strand itself, not the follicle beneath the scalp.
