Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. The hair captures a retrospective record of alcohol and drug use by encapsulating biomarkers within the hair's fibers as it grows. When clipped close to the scalp, hair can offer up to a roughly 3-month detection timeframe for alcohol and drugs. Hair collection is straightforward, somewhat resistant to tampering, and easy to transport.
A 1.5-inch segment with around 200 hair strands (approximately the thickness of a #2 pencil) nearest the scalp yields 100mg of hair, the optimal sample size for testing and validation. For EtG, additional tests, and/or tests exceeding 10 panels, it is advised to collect 150mg of the sample. We advise weighing the sample using a jeweler’s scale. If scalp hair is not available, an equivalent quantity of body hair may be gathered. When referring to head hair, we specifically mean scalp hair. Body hair includes all other hair forms (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result consists of four major steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves initially processing a sample into a lab’s system. It encompasses ensuring the sample was sealed and transported correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry not furnished by an electronic chain of custody system.
Screening provides a preliminary rapid check for drugs of abuse. Although Screening is an affordable approach to dismiss drug use in most samples, a positive result requires confirmation to be valid in court. Samples that test presumptively positive during Screening necessitate a secondary verification.
If a specimen is presumptively positive during Screening, additional hair is extracted from the initial sample and prepped for Extraction. In this stage, substances are extracted from hair at significantly lower concentrations than in other methods (e.g., urine or oral fluid), which makes hair drug screening the most challenging method to execute.
Positive screening results are verified using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are presumptively positive undergo washing before confirmation as required. The comprehensive lab process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 standards accreditation.

Limitations:
Note: Although commonly called "hair follicle tests," the test in fact analyzes the hair strand, not the follicle beneath the scalp.
