Hair testing is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair captures biomarkers within its fibers, offering a prolonged record of substance use. When collected near the scalp, hair can detect drugs and alcohol for roughly a three-month period. The collection process for hair is straightforward, with minimal likelihood of tampering, and it can be conveniently shipped.
A 1.5-inch sample, consisting of approximately 200 hair strands (similar in size to a #2 pencil) near the scalp, yields 100mg of hair, suitable for both screening and confirmation. For EtG evaluations, additional testing, or panels exceeding 10, a sample of 150mg is advised. We suggest using a jeweler’s scale for precise measurement. If scalp hair cannot be obtained, an equal quantity of body hair might be used. "Head hair" specifically refers to scalp hair, whereas "body hair" encompasses other types like facial or axillary hair.
Process Overview
There are four primary stages in the laboratory analysis of drug test results: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the step in which a sample is initially processed within a lab's system. This process includes ensuring the sample is sealed and transported correctly, assigning a unique LAN (Laboratory Accessioning Number), and completing any necessary data entry that wasn't captured by an electronic chain of custody system.
Screening consists of a preliminary assessment for potential drug abuse. While cost-effective for ruling out drug usage in numerous samples, a positive screen must be confirmed for it to be legally admissible. Samples deemed presumptively positive during Screening necessitate further confirmation.
When a sample tests presumptively positive during the Screening phase, more hair is extracted from the original sample for preparation in the Extraction phase. Drugs are then extracted from the hair, at lower concentrations than with other methods (e.g., urine or oral fluid), highlighting why hair drug screening is a challenging process.
Positive screening results undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. All samples testing positive are cleaned before Confirmation as necessary. The entire laboratory procedure, from Accessioning to Confirmation, falls under review by both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Limitations:
Note: While often called "hair follicle tests", the analysis focuses on the hair strand itself, rather than the follicle beneath the scalp.
