Hair analysis is now recognized as an effective method for detecting drug and alcohol usage. Hair captures biomarkers within the strands, offering a comprehensive timeline of substance use. When sampled near the scalp, hair can reveal drug or alcohol use over an estimated three-month period. Collecting hair is straightforward, relatively tamper-proof, and easy to transport.
A 1.5-inch segment of roughly 200 hair strands, similar in size to a #2 pencil, close to the scalp provides around 100mg, the optimal quantity for testing. For EtG, additional tests, and/or testing beyond 10 panels, 150mg is advisable. A jeweler’s scale is recommended for weighing the sample. If scalp hair cannot be obtained, an equivalent amount of body hair is acceptable. Note that "head hair" refers strictly to scalp hair, while "body hair" encompasses all other types (facial, axillary, etc.).
Process Overview
Four primary stages comprise the laboratory processing of drug test outcomes: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial incorporation of a sample into the laboratory system, ensuring proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any necessary additional data entry that the electronic chain of custody system does not provide.
Screening consists of a preliminary drug-of-abuse check. Although Screening effectively eliminates drug usage in most cases, positive results require confirmation to be considered legally acceptable. Samples showing presumptive positives in Screening need secondary confirmation.
If Screening suggests a positive, additional hair is extracted from the original sample and prepped for Extraction. In Extraction, drugs are drawn out from hair at a lower concentration than other methods (e.g., urine or oral fluid), which makes hair testing particularly challenging.
Any positive screening outcomes undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are washed before Confirmation as necessary. The comprehensive laboratory procedure, from Accessioning to Confirmation, adheres to both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.

Note: While often labeled as "hair follicle tests", the test evaluates the hair shaft rather than the follicle beneath the skin.
