Recognized as a potent approach for identifying substance usage, hair testing allows for an extended review of alcohol and drugs. Hair secures long-term evidence, capturing biomarkers within the strand’s fibers as they grow. With a sample near the scalp, there is potential for up to a 90-day detection span regarding alcohol and drugs. Collection is straightforward, tampering is challenging, and shipping is uncomplicated.
The optimal sample, a 1.5-inch segment consisting of roughly 200 strands of hair (approximately pencil thickness), yields 100mg, suitable for both screening and confirmation. For EtG or tests exceeding 10 panels, 150mg is advised. Weighing is best conducted on a jeweler’s scale. Should scalp hair be absent, comparable body hair is an option. “Head hair” refers solely to scalp hair, while “body hair” encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory process for processing drug test outcomes includes four essential steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase where a sample is processed into a lab’s system. This phase ensures proper sealing and shipment of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes any extra data input absent from an electronic chain of custody system.
Screening consists of a preliminary check for drug abuse. Although screening is cost-efficient to exclude drug use on most samples, confirmation is essential for positive results to be valid in court. Samples that are likely positive in Screening require a further confirmation.
If Screening declares a sample likely positive, additional hair from the initial sample is set for Extraction. Here, drugs are separated from hair at a significantly reduced concentration compared to other methods (e.g., urine or oral fluid), establishing hair drug screening as the most challenging method.
Positive screening confirmations are done through GC/MS, GC/MS/MS, or LC/MS/MS. Necessary washing is performed before confirming all presumptive positive samples. The entire lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair standard and ISO / IEC 17025 accreditation.

Note: Commonly termed as "hair follicle tests", the analysis targets the strand, not the follicle below the scalp.
