Urine| Hair Follicle | Oral Fluid | Blood | ETG
Hair analysis has emerged as a robust method for spotting alcohol and drug consumption. The hair traps biomarkers in its fibers, offering an extended history of substance use. Gathering hair near the scalp provides a detection timeframe of up to around 90 days for alcohol and drugs. Collecting hair is straightforward, challenging to tamper with, and convenient to send.
A 1.5-inch section containing roughly 200 hairs (equivalent to a #2 pencil's thickness) near the scalp delivers 100mg of hair, perfect for both screening and confirmation. For EtG, additional tests, and tests exceeding 10 panels, a 150mg sample is suggested. Using a jeweler’s scale to weigh the sample is advisable. For cases lacking scalp hair, a similar quantity of body hair is acceptable. Head hair strictly refers to scalp hair. Body hair encompasses all other types (beard, underarm, etc.).
Process Overview
Four primary phases constitute the lab processing of a drug test outcome: Accessioning, Screening, Extraction, and Confirmation.
Accessioning begins with the primary integration of a sample into the lab system. This includes checking for correct sealing and shipment of the sample, assigning a random LAN (Laboratory Accessioning Number), and performing any extra data entry not handled by an electronic chain of custody system.
Screening executes a preliminary drug abuse check. Although Screening offers a cost-efficient means to rule out drug use in most samples, any positive screening results need verification for legal admissibility. Any samples that show presumptive positives in Screening necessitate a subsequent confirmation.
Should a sample exhibit a presumptive positive during Screening, additional hair is extracted from the original sample and readied for Extraction. In this phase, extracting drugs from hair occurs at significantly lower concentrations compared to other methods (e.g., urine or oral fluid), hence why hair drug screening is the most challenging method to perform.
All positive Screening results undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples are washed if necessary. The entire lab procedure from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Note: Commonly misunderstood as "hair follicle tests", the test examines the hair strand, not the follicle beneath the scalp.
