Hair testing is widely recognized as an effective means to detect drug and alcohol consumption. The hair offers an extended historical record by encapsulating biomarkers within the fibers of the hair strand as it grows. When collected near the scalp, hair can reveal drug and alcohol use over a period of up to three months. It's straightforward to collect, relatively tough to tamper with, and convenient to send.
A 1.5-inch sample comprising around 200 hair strands (approximately the size of a #2 pencil) closest to the scalp yields 100mg of hair, which is the optimal sample size for both screening and confirmation. For EtG, additional panels, and tests beyond the standard 10 panels, it is advisable to have 150mg of the specimen. Measuring the specimen with a jeweler’s scale is suggested. If scalp hair isn't obtainable, an equivalent amount of body hair can be taken. When mentioning head hair, we exclusively mean scalp hair. Body hair includes all other types of hair (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result consists of four main steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial handling of a sample within a laboratory’s framework. This step verifies the proper sealing and shipment of the sample, assigns a random LAB (Laboratory Accessioning Number), and finalizes any supplementary data entry absent from an electronic chain of custody system.
Screening acts as a preliminary examination for drug abuse indicators. While it serves as an economical method to eliminate drug consumption possibilities in most samples, a positive screen qualifies only following confirmation for legal admissibility. Any samples flagged as presumptively positive during Screening necessitate further confirmatory analysis.
Should a sample show a presumptive positive result during Screening, additional hair from the initial sample is processed for Extraction. At this phase, drug elements are extracted from hair at significantly lower concentrations compared to alternate procedures (e.g., urine or oral fluid), positioning hair drug screening as the most complex technique to execute.
Confirmation of any positive screening outcome is performed through methods such as GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all samples with presumptive positive results undergo washing as required. The comprehensive lab process, from Accessioning to Confirmation, undergoes evaluation under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
