Hair testing is recognized for its capabilities in detecting drug and alcohol consumption. Hair captures a long-term account of alcohol and drug use through biomarkers in the strands of growing hair. When obtained near the scalp, hair offers a detection timeline of approximately 3 months for alcohol and diverse drugs. Hair collection is straightforward, difficult to tamper with, and convenient to transport.
A 1.5-inch segment consisting of about 200 hair strands (akin to the diameter of a #2 pencil) from the scalp yields 100mg of hair, which is the desired quantity for analysis. For EtG, specialized panels, or tests exceeding 10 panels, 150mg of hair is preferred. Utilizing a jeweler’s scale to weigh the sample is advisable. If scalp hair is not an option, a similar volume of body hair can be collected. Head hair specifically indicates scalp hair, whereas body hair encompasses other types (such as facial, axillary, etc.).
Process Overview
The lab processing of a drug test involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial stage where a sample enters the laboratory's system. This step includes checking that the sample was properly sealed and delivered, creating a random LAN (Laboratory Accessioning Number), and finalizing any missing data not handled by an electronic custody system.
Screening performs a preliminary assessment for drugs. Although Screening is efficient in eliminating drug presence in most samples, a positive result must be verified for court validity. Samples yielding a positive result in Screening necessitate further confirmation.
Should a sample test positive during Screening, additional hair is extracted from the original sample and processed for Extraction. This stage isolates drugs from hair at a more diluted concentration than other methods (e.g., urine or saliva), which accounts for the complexity of hair drug screening.
Confirmation of a positive Screening outcome is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo washing before confirmation if required. Both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards govern the entire lab process from Accessioning to Confirmation.
