Hair analysis has gained recognition as an effective method for identifying drug and alcohol consumption. Hair captures long-term evidence of alcohol and drug usage by holding biomarkers within its strands. When segments are cut near the scalp, they can offer up to an estimated three-month period for detecting alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and simple to transport.
A 1.5-inch sample consisting of roughly 200 hair strands (comparable in thickness to a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the preferred quantity for screening and validation. For tests like EtG and those exceeding 10 panels, 150mg of hair is suggested. It’s advisable to measure the hair using a jeweler’s scale. If head hair is unavailable, an equivalent amount of body hair may be used. Here, head hair refers exclusively to scalp hair, while body hair encompasses all other types, such as facial and underarm hair.
Process Overview
The primary phases in processing a drug test in a lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning covers the beginning steps of entering a sample into a laboratory, which includes ensuring the sample was properly sealed and dispatched, assigning a Laboratory Accessioning Number (LAN) at random, and completing any additional data entry absent from an electronic chain of custody.
Screening acts as a preliminary and rapid appraisal for substances of abuse. Although it effectively rules out drug use for many samples, a positive indication requires further confirmation to be legally valid. Samples indicating possible drug presence during Screening must undergo additional verification.
Samples indicating a possibility of drug presence during the Screening process necessitate extracting more hair from the original sample for further preparation in the Extraction stage. This phase extracts drugs from hair at much finer concentrations compared to methods like urine or saliva testing, making hair analysis more challenging.
Confirmation for any positive result during Screening uses techniques like GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before Confirmation if necessary. The complete lab procedure, from Accessioning to Confirmation, undergoes review under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards.

Limitations:
Note: Although frequently termed as "hair follicle tests," these tests evaluate the hair strand itself instead of the follicle beneath the scalp.
