Hair testing is increasingly regarded as an effective method for uncovering drug and alcohol consumption. By encapsulating biomarkers in the fibers of the developing hair strand, hair offers a comprehensive history of alcohol and other substances. When harvested near the scalp, hair can reveal alcohol and other drug use for an evaluation period of up to three months. Collecting hair is straightforward, tampering with it is relatively challenging, and it's convenient for transport.
A 1.5-inch section of about 200 hair strands (roughly the dimension of a #2 pencil) nearest to the scalp yields 100mg of hair, the preferred quantity for assessment and validation. For EtG, supplementary tests, and collections exceeding 10 panels, a 150mg sample is advisable. Using a jeweler’s scale to measure the sample is recommended. If head hair is absent, a comparable quantity of body hair can be collected. Head hair pertains solely to scalp hair, while body hair encompasses all other varieties (facial, axillary, etc.).
Process Overview
The laboratory evaluation of a drug test result encompasses four crucial stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of initially entering a sample into a laboratory’s framework. This stage checks that the sample has been sealed and delivered correctly, allocates a unique LAN (Laboratory Accessioning Number), and completes any further data input absent from an electronic chain of custody system.
Screening is a preliminary rapid evaluation for drug abuse. Although Screening is a budget-friendly method to dismiss drug use in most samples, a favorable screen necessitates confirmation to stand in legal settings. Any samples with a presumptive positive during Screening require further confirmation.
If Screening indicates a presumptive positive, additional hair is extracted from the original sample for the Extraction phase. In this process, drugs are extracted from hair at notably lower concentrations compared to other methodologies (such as urine or oral fluid), rendering hair drug screening the most complex methodology to execute.
Positive screening confirmations are conducted with GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples undergo washing before confirmation, as necessary. The complete laboratory cycle from Accessioning to Confirmation is scrutinized in alignment with both the CAP (College of American Pathologists) Hair designation and accreditation under ISO / IEC 17025 standards.
