Hair analysis has evolved into a significant method for identifying substance and alcohol usage. Hair fibers can capture biomarkers, offering a long-term record of drug and alcohol consumption as the hair grows. When gathered near the scalp, hair can indicate drug or alcohol usage for up to three months. Collecting hair is straightforward, hard to tamper with, and easy to transport.
Collecting a 1.5-inch hair segment, around 200 strands (comparable to a #2 pencil), nearest to the scalp provides 100mg, which is optimal for testing and validation. For tests involving EtG or including more than 10 panels, a 150mg sample is advisable. Utilizing a jeweler's scale to measure the specimen is suggested. If scalp hair isn't accessible, equivalent body hair can be used. 'Head hair' specifies only scalp hair, whereas 'body hair' encompasses all other hair forms (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails entering a sample into a lab's system, which covers ensuring the sample was correctly sealed and sent, creating a random LAN (Laboratory Accessioning Number), and completing any data input not covered by an electronic chain of custody.
Screening serves as a preliminary assessment for drug presence. It's a cost-efficient strategy to exclude drug use for most samples, but any positive screen must be verified to be defensible legally. Presumptive positives from Screening must undergo confirmation.
Presumptive positive cases from Screening lead to further hair extraction from the original sample for Extraction, where drugs are taken out at lower concentrations than in other methods like urine or oral fluids. This complexity makes hair drug screening challenging.
Through GC/MS, GC/MS/MS or LC/MS/MS, any positive screening results are confirmed. Presumptive positive samples undergo washing before confirmation as appropriate. The entirety of the process from Accessioning to Confirmation is examined under both CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.

Note: Although often labeled as "hair follicle tests," the procedure examines the hair strand, not the follicle beneath the skin.
