Hair analysis is now acknowledged as an effective means for identifying drug and alcohol consumption. Hair acts as a repository for alcohol and drug traces by encasing biomarkers in the fibers of the hair as it grows. When taken near the root, hair samples can offer up to an estimated 90-day window for detecting alcohol and substances. Collecting hair is straightforward, challenging to tamper with, and easy to transport.
A sample of 1.5 inches with about 200 hairs (equivalent to a #2 pencil’s girth) near the scalp yields 100mg of hair, optimal for screening and verification. For EtG, add-ons, and/or panels exceeding 10, 150mg is advised. Using a jeweler’s scale to weigh the sample is recommended. If scalp hair isn’t available, an equivalent volume of body hair is acceptable. "Head hair" specifically refers to scalp hair. "Body hair" encompasses all other hair types (such as facial or axillary).
Process Overview
The laboratory procedure for processing a drug test result comprises four primary stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is initially logged into a lab’s system. This process ensures the sample was properly sealed and dispatched, assigns a unique LAN (Laboratory Accessioning Number), and completes any extra data entry not covered by an electronic chain of custody system.
Screening involves a preliminary evaluation for common drugs. While Screening is an economical method to negate drug consumption in most samples, a Screen-positive result requires confirmation for legal admissibility. Samples that are preliminarily positive at the Screening stage require additional verification.
Should a sample show preliminary positives during Screening, additional hair is taken from the primary specimen for Extraction. Here, substances are isolated from hair at far lower concentrations than other approaches (like urine or oral fluids), which makes hair drug analysis the most intricate method available.
Positive Screening results must be verified through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo cleaning before confirmation if necessary. The entire lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation standards.

Note: Although commonly termed "hair follicle tests," the analysis is performed on the hair strand itself, not on the follicle beneath the scalp.
