Hair testing is increasingly recognized as an effective means for detecting substance use. Hair retains a long-term record of alcohol and drug consumption by trapping biomarkers in the strands. When hair is collected near the scalp, it offers a detection window of up to about 90 days for alcohol and drugs. Hair collection is straightforward, hard to tamper with, and easily transportable.
A 1.5-inch section containing around 200 strands of hair (similar to the size of a #2 pencil) from the scalp provides 100mg of hair, the recommended sample size for testing. For EtG, additional tests, and/or over 10-panel tests, a 150mg sample is advisable. It is suggested to weigh the hair sample on a jeweler’s scale. If scalp hair is unavailable, a similar amount of body hair may be collected. "Head hair" should be interpreted as scalp hair only, whereas "body hair" encompasses other hair types (like facial, axillary, etc.).
Process Overview
The four primary steps in the laboratory analysis of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary processing phase of incorporating a sample into the lab's system. This step involves verifying the sample's secure sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing any necessary data recording not handled by an electronic chain of custody system.
Screening is a preliminary check for substance abuse. It is a cost-efficient method to exclude drug use in most samples; however, a positive screening necessitates confirmation to hold up in court. Any presumptively positive samples in Screening need additional confirmation.
If a sample tests positive in Screening, further hair is extracted from the original sample and prepped for Extraction. Drugs are isolated from hair at lower concentrations compared to other techniques (such as urine or oral fluid), making hair drug screening the most challenging methodology to conduct.
Confirmation of any positive screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Every presumptively positive sample undergoes washing before confirmation as required. The entire procedure from Accessioning to Confirmation is scrutinized under CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Limitations:
Note: Even though referred to as "hair follicle tests", the analysis is conducted on the hair strand rather than the follicle under the scalp.
