Hair analysis has become recognized as an effective instrument for identifying the use of drugs and alcohol. Hair offers a comprehensive history of substance use by encapsulating biomarkers within the fibers of the hair as it grows. When obtained near the scalp, hair can provide a detection window of approximately three months for alcohol and other substances. Hair collection is straightforward, somewhat challenging to tamper with, and easy to transport.
A 1.5-inch segment of about 200 hair strands, roughly the width of a #2 pencil, cut closest to the scalp, yields 100mg of hair, the optimal quantity for both screening and confirmation. For EtG, add-ons, or tests exceeding 10 panels, a 150mg sample is suggested. Measuring the sample on a jeweler’s scale is advisable. If scalp hair is not accessible, an equivalent quantity of body hair can be collected. In this context, head hair pertains solely to scalp hair, whereas body hair includes all other types (facial, axillary, etc.).
Process Overview
The laboratory procedure for drug test results encompasses four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial stage where a sample is processed into the lab's system, which includes verifying proper sealing and shipment of the sample, assigning it a random LAN (Laboratory Accessioning Number), and completing supplementary data entry lacking from an electronic chain of custody system.
Screening provides a preliminary assessment for drug presence. Although Screening is an economical method to exclude drug usage for most samples, a positive screen requires a confirmation to be valid in legal proceedings. Samples showing presumptive positive results in Screening mandate secondary confirmation.
For samples with presumptive positive results in Screening, additional hair is extracted from the initial sample and prepared for the Extraction phase. In this phase, substances are isolated from the hair at significantly lower concentrations than other methodologies (e.g., urine or oral fluid), which contributes to the complexity of hair drug screening.
Confirmation of any positive screening result is conducted via GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples are cleansed as necessary. The laboratory procedures from Accessioning to Confirmation are audited under both the CAP (College of American Pathologists) Hair designation and the ISO/IEC 17025 accreditation standards.

Note: Though frequently called "hair follicle tests," the evaluation is performed on the hair strand itself, not the follicle beneath the scalp.
