Hair analysis is now recognized as an effective means for revealing drug and alcohol consumption. Hair offers a prolonged record of alcohol and drug use by capturing biomarkers within the strands as they grow. When samples are taken from near the scalp, they can offer a detection period of up to roughly three months for alcohol and drugs. Hair collection is straightforward, relatively challenging to tamper with, and convenient to transport.
A sample measuring 1.5 inches and containing around 200 hair strands (approximately the diameter of a #2 pencil) taken nearest to the scalp yields about 100mg of hair, the optimal sample for both screening and verification. For EtG, add-ons, or screenings exceeding 10 panels, a 150mg specimen is advisable. We suggest weighing the sample on a jeweler's scale. Should scalp hair be absent, an equivalent quantity of body hair can be gathered. When mentioning head hair, we solely mean scalp hair. Body hair encompasses all other varieties (facial, axillary, etc.).
Process Overview
The primary stages in the lab processing of a drug test result consist of Accessioning, Screening, Extraction, and Confirmation.
Accessioning is about integrating the sample initially into a lab's operations. This step involves ensuring the sample was correctly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing any further data entries not supplied by an electronic custody chain system.
Screening is a preliminary rapid evaluation for substance abuse. While cost-efficient for excluding drug use in most samples, a positive screening must be verified for court admissibility. Any samples registering presumptively positive in Screening necessitate a follow-up confirmation.
If a sample is presumptively positive during Screening, extra hair is extracted from the original sample for the Extraction stage. Here, drugs are extracted from hair at a substantially lower level than other methods (e.g., urine or oral fluid), explaining why hair drug screening is the most intricate method to conduct.
Verification of any positive screening outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives are cleansed before confirmation as necessary. The comprehensive lab procedure, from Accessioning through Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards.

Note: Even though often called "hair follicle tests", the analysis actually examines the hair strand and not the follicle beneath the scalp.
