Hair testing is regarded as a robust method for identifying drug and alcohol consumption. Hair captures a prolonged history of alcohol and drugs by sequestering biomarkers within the fibers of the developing hair strand. When sourced near the scalp, hair can offer up to about a 3-month period for alcohol and drug detection. Hair is straightforward to gather, relatively hard to tamper with, and simple to transport.
Gathering a sample of 1.5 inches consisting of roughly 200 hair strands (comparable to a #2 pencil's thickness) nearest to the scalp will provide 100mg, which is the perfect sample quantity for screening and confirmation. For EtG, add-ons, and/or assessments exceeding 10 panels, a 150mg specimen is advised. It is recommended to weigh the sample on a jeweler’s scale. If scalp hair is unavailable, an equivalent quantity of body hair can be collected. When discussing head hair, we specifically mean scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The primary stages in processing a drug test result in the laboratory include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary entry of a sample into the laboratory’s framework. This incorporates ensuring the sample was correctly sealed and delivered, allocating a random LAN (Laboratory Accessioning Number), and completing any supplementary data input absent in an electronic chain of custody system.
Screening performs an initial rapid assessment for drugs of abuse. Although Screening is a cost-efficient method to discard drug usage in most samples, any positive screen requires confirmation for it to be court-admissible. Samples that show a presumptive positive in Screening need further confirmation.
Should a specimen show a presumptive positive during Screening, additional hair is extracted from the original specimen for Extraction preparation. At this stage, drugs get extracted from hair at a significantly lower concentration level compared to other methods (such as urine or oral fluid), which accounts for why hair drug screening is the most challenging methodology to execute.
Positive screening results receive Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation as necessary. The entire process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
