Hair analysis has increasingly become recognized as an effective means for identifying drug and alcohol consumption. Hair captures long-term evidence of alcohol and drug intake by embedding biomarkers within the fibers of the hair as it grows. When taken from near the scalp, hair can reveal a detection time frame of up to about 3 months for alcohol and drugs. Hair is straightforward to obtain, relatively challenging to tamper with, and convenient to transport.
A 1.5-inch segment consisting of roughly 200 hair strands (similar in size to a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal sample for analysis and confirmation. For EtG, additional tests, and/or analyses exceeding 10 panels, 150mg of the sample is ideal. It is advisable to weigh the sample with a jeweler’s scale. If there is no available scalp hair, a similar quantity of body hair can be substituted. The term head hair refers exclusively to scalp hair. Body hair encompasses all other hair varieties (facial, axillary, etc.).
Process Overview
The main procedures in the laboratory analysis of a drug test result encompass Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial steps of incorporating a sample into a laboratory’s system. This involves verifying the proper sealing and shipping of the sample, assigning a unique LAN (Laboratory Accessioning Number), and completing necessary data entry not furnished by an electronic chain of custody system.
Screening entails a preliminary rapid assessment for substances of abuse. While Screening is an economical method to eliminate drug use for most samples, a screened positive outcome requires verification to be valid in a legal context. Any samples assumed positive in Screening necessitate subsequent confirmation.
If a sample tests as presumptively positive during the Screening phase, additional hair is extracted from the initial sample and readied for Extraction. In this phase, drugs are isolated from hair at a much lower concentration than in alternate methodologies (such as urine or oral fluid), rendering hair drug analysis the most rigorous methodology to execute.
Validation of any screened positive result is accomplished via GC/MS, GC/MS/MS, or LC/MS/MS. All samples assumed positive undergo washing before confirmation when necessary. The whole laboratory procedure, from Accessioning to Confirmation, is assessed under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.

Limitations:
Note: Despite often being labeled as "hair follicle tests", the testing examines the hair strand rather than the follicle beneath the scalp.
Why Hair Follicle Testing Beats Urine Testing in Dallas, NC, comes down to several key advantages.
