Hair testing is recognized as an effective method for detecting drug and alcohol consumption. By capturing biomarkers within the fibers of the hair strands as they grow, hair offers a prolonged history of substance use. When collected near the scalp, hair can provide nearly a 3-month detection timeframe for alcohol and drugs. Hair is easy to collect, somewhat resistant to tampering, and convenient to transport.
A sample of 1.5 inches, consisting of approximately 200 hair strands (around the size of a #2 pencil) closest to the scalp, offers 100mg of hair, which is optimal for analysis and verification. For EtG, add-ons, and/or tests beyond 10 panels, 150mg is advised, with the specimen ideally weighed on a jeweler’s scale. If scalp hair is unavailable, an equivalent amount of body hair is acceptable. "Head hair" specifically refers to scalp hair, while "body hair" encompasses all other hair varieties (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result comprises four crucial steps: Accessioning, Screening, Extraction, and Confirmation.
In Accessioning, the sample undergoes initial processing into the laboratory's system, which includes verifying proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and completing additional data entry not covered by an electronic custody system.
Screening is a preliminary assessment for drug abuse. While screening is a cost-efficient method for eliminating drug use in most samples, any positive finding must be validated for court acceptance. Any samples presumed positive in Screening necessitate further confirmation.
Should a sample test presumptively positive during Screening, additional hair is extracted from the original specimen for Extraction. In this stage, drug extraction from hair occurs at significantly lower concentrations than other methods (e.g., urine or oral fluid), making hair drug screening the most challenging methodology to execute.
Positive screening results are confirmed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo a wash pre-confirmation, if required. The complete laboratory process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
