Hair testing is increasingly recognized as an effective means for identifying drug and alcohol consumption. Hair serves as a long-term record by capturing biomarkers within the fibers of the hair as it grows. When obtained near the scalp, hair can offer a detection period of up to 3 months for alcohol and drugs. Hair collection is straightforward, resistant to tampering, and easily transportable.
A sample measuring 1.5 inches, containing around 200 hair strands (roughly the diameter of a #2 pencil) near the scalp yields 100mg of hair, ideal for analysis and verification. For EtG, additional tests, and/or panels exceeding 10, a 150mg sample is advisable. Utilizing a jeweler’s scale is recommended for measuring the specimen. If scalp hair cannot be collected, a similar amount of body hair may be used. Reference to head hair is specific to scalp hair. Body hair includes all other types (such as facial, axillary, etc.).
Process Overview
The core stages in lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary step of introducing a sample into the laboratory system. This stage ensures the sample was properly sealed and transported, assigns it a random LAN (Laboratory Accessioning Number), and completes any missing data that the electronic chain of custody system doesn’t provide.
Screening is a preliminary assessment for drugs of abuse. Although Screening is efficient for ruling out drug use in most samples, any positive findings require confirmation for legal validation. Samples with presumptive positive results during Screening necessitate secondary verification.
When a sample tests positive during Screening, additional hair is taken from the initial sample and prepped for Extraction. During Extraction, drugs are isolated from hair at much lower concentrations compared to other techniques (such as urine or oral fluid), making hair drug screening more complex.
Positive screening results are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. Any samples presumed positive are washed before confirmation if necessary. The complete lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation.

Note: Despite being commonly called "hair follicle tests", the examination targets the hair strand rather than the follicle beneath the scalp.
