Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. It offers a comprehensive timeline of alcohol and drug intake by capturing biomarkers within the fibers of the growing hair shaft. When sampled near the scalp, hair allows for an approximate 3-month timeframe for detecting substances. Hair is straightforward to collect, not easily tampered with, and convenient for shipping.
An optimal sample consists of a 1.5-inch section with roughly 200 hair strands (about #2 pencil thickness) closest to the scalp, amounting to 100mg of hair, which is ideal for both screening and confirmation. For EtG tests, add-ons, or panels exceeding 10, a specimen weighing 150mg is advised. Utilizing a jeweler's scale for weighing the hair is suggested. If scalp hair is unavailable, a similar quantity of body hair can be used. "Head hair" refers exclusively to scalp hair, whereas "body hair" includes all other types (facial, axillary, etc.).
Process Overview
The key stages in the lab analysis of a drug test result involve Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the preliminary processing of a sample into the lab's system. This process ensures the sample is properly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and finalizes any additional data input if not already covered by an electronic chain of custody.
Screening provides a preliminary check for drug abuse. Although cost-effective for ruling out drug use in most samples, any positive findings in Screening need confirmation for legal admissibility. Samples testing presumptively positive in Screening necessitate additional verification.
Presumed positive samples in the Screening phase require extra hair extraction from the original sample for the Extraction stage. During this stage, drug traces are extracted from hair at much lower concentrations compared to other methods (ex. urine or oral fluid), which explains why hair drug screening is among the most complex methodologies.
Positive screening results are confirmed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives receive a wash prior to confirmation as needed. The complete laboratory workflow from Accessioning to Confirmation undergoes review under both CAP (College of American Pathologists) Hair criteria and accreditation to ISO / IEC 17025 standards.

Note: Referred to commonly as "hair follicle tests", the actual test examines the hair strand, not the follicle below the scalp.
