Hair analysis has emerged as a robust means for identifying drug and alcohol consumption. Hair strands capture biomarkers within their fibers, creating a comprehensive history of drug use. When hair is cut near the scalp, it can reveal substance usage within a window of roughly three months. Collection is straightforward, tampering is relatively challenging, and transportation is uncomplicated.
A sample measuring 1.5 inches with approximately 200 hair strands (similar in size to a #2 pencil) from near the scalp yields 100mg of hair, which is optimal for both screening and confirmation. For EtG, optional components, and tests exceeding 10 panels, 150mg of hair is advisable. Using a jeweler’s scale for measurement is recommended. If scalp hair cannot be obtained, a proportional quantity of body hair can be used. References to head hair specifically denote scalp hair, whereas body hair includes all other varieties (facial, axillary, etc.).
Process Overview
The four critical stages in processing a drug test in the lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves incorporating a sample into the laboratory’s processes. This step ensures the sample was properly sealed and delivered, generates a random LAN (Laboratory Accessioning Number), and addresses additional data entry requirements not already provided by an electronic chain of custody.
Screening provides an initial assessment for substances of misuse. As an economical approach, Screening helps dismiss drug presence in most samples, but any positive findings require confirmation for legal acceptability. Presumptively positive samples from Screening necessitate follow-up confirmation.
If a sample tests presumptively positive during Screening, additional hair is extracted from the sample and prepared for further analysis. Drugs are extracted from hair at notably lower concentrations than in other methods (e.g., urine or oral fluids), presenting a greater challenge in execution for hair drug screening.
Confirmation of any positive screening is pursued using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, any presumptively positive samples undergo washing as needed. The lab process from Accessioning to Confirmation adheres to CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standard accreditation.

Note: Although commonly termed "hair follicle tests," the examination pertains to the hair strand rather than the follicle beneath the scalp.
