Hair analysis is increasingly recognized as a valuable method for identifying substance use. Hair retains biomarkers of drugs and alcohol within the strands' fibers, providing a comprehensive timeline of usage. A sample collected near the scalp can offer insights into drug and alcohol use for up to three months. Hair is straightforward to collect, challenging to tamper with, and simple to send.
An ideal hair sample measures 1.5 inches and consists of about 200 hair strands (akin to a #2 pencil in thickness), yielding 100mg of hair for thorough screening and verification. For EtG, additional testing, and tests beyond ten panels, 150mg of hair is preferable. We suggest using a jeweler’s scale for weighing the specimen. If scalp hair is inaccessible, body hair of similar volume can be used. “Scalp hair” refers exclusively to cranial hair, while “body hair” pertains to all other hair forms (e.g., facial, axillary).
Process Overview
The key stages in processing a drug test in a lab include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves integrating a sample into a lab's framework, which includes checking the sample's appropriate sealing and shipping, generating a unique LAN (Laboratory Accessioning Number), and completing any extra data entry not covered by an electronic chain of custody.
Screening serves as a preliminary evaluation for drug presence. It's a cost-efficient method for excluding drug use in most cases, though a positive result requires confirmation for legal acceptability. Samples with a presumptive positive outcome in Screening necessitate further verification.
When a Screening yields a presumptive positive, additional hair is extracted from the original sample for the Extraction phase. Here, substances are isolated from hair at lower concentrations than other methods (e.g., urine or saliva), highlighting the complexity of hair drug analysis.
Confirmation of a positive outcome uses GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples undergo washing prior to verification if needed. The entire laboratory procedure, from Accessioning through Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair classification and ISO/IEC 17025 standards accreditation.

Note: The test, though often termed a “hair follicle test,” targets the hair strand, not the follicle beneath the skin.
