Hair testing is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair captures a longitudinal record of alcohol and other drugs by embedding biomarkers within the fibers of the growing hair strand. When taken near the scalp, it can offer as much as a three-month detection timeframe for both alcohol and other drugs. Hair is straightforward to gather, difficult to alter, and simple to transport.
A sample of hair measuring 1.5 inches and consisting of approximately 200 strands (similar in circumference to a #2 pencil) nearest the scalp will provide 100mg of hair, which is the preferred amount for both screening and confirmation. For EtG, additional tests, and/or panels exceeding ten, a sample of 150mg is advised. It's best to measure the sample using a jeweler's scale. Should scalp hair be lacking, an identical quantity of body hair can be used. When mentioning head hair, we specifically refer to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The process of lab testing for drugs incorporates four principal steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the first integration of a sample into a lab’s system. This consists of confirming the sample was sealed and transported appropriately, creating a random LAN (Laboratory Accessioning Number), and completing any data entry missing in an electronic chain of custody system.
Screening consists of a primary quick analysis for drugs of abuse. Although Screening provides an economical way to discount drug use in most cases, a positive screen must be confirmed for legal validity. Any samples presumptively positive in Screening must undergo further confirmation.
If a sample indicates a presumptive positive during the Screening phase, additional hair is taken from the initial batch and readied for Extraction. During this phase, drugs are extracted from hair at much reduced concentrations compared to other methods (e.g., urine or oral fluid), making hair drug testing particularly challenging to execute.
Confirmation of any positive screening outcome is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicating presumptive positivity are cleaned before confirmation as necessary. The comprehensive lab process, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Limitations:
Note: While commonly termed "hair follicle tests", the examination focuses on analyzing the hair strand rather than the follicle under the scalp
