Hair testing is recognized as a robust method for identifying drug and alcohol consumption. Hair captures a historical record of substance use by embedding biomarkers within the fibers of growing strands. When taken close to the scalp, hair provides a detection timeframe of up to 90 days for alcohol and drugs. Hair collection is straightforward, moderately resistant to tampering, and easy to transport.
A 1.5-inch sample of roughly 200 hair strands, comparable to the thickness of a #2 pencil, near the scalp provides 100mg, ideal for screening and confirmation. For EtG, extended panels, and tests beyond 10 panels, 150mg is advised. Utilizing a jeweler’s scale to weigh the specimen is recommended. If scalp hair isn't available, an equal quantity of body hair is acceptable. "Head hair" refers strictly to scalp hair; "body hair" encompasses all other types (such as facial or axillary).
Process Overview
The laboratory processing of a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
In Accessioning, samples undergo initial processing within a laboratory’s framework. This step includes ensuring the sample is properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and finalizing any data entries missing from an electronic chain of custody system.
Screening entails a preliminary check for drugs of abuse. Although cost-effective for eliminating drug usage in most samples, positive screens require confirmation for court admissibility. Samples indicating presumptive positivity in Screening necessitate further confirmation.
Presumptively positive samples in Screening lead to additional hair being extracted from the original specimen for Extraction. During this stage, drugs are isolated from hair at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), which makes hair drug screening the most intricate methodology.
Confirmation for positive screening outcomes is accomplished using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing as needed before confirmation. The entire process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair standards and accreditation to ISO / IEC 17025 standards.

Note: Though often called "hair follicle tests", the analysis is conducted on the hair strand rather than the follicle beneath the scalp.
