Hair testing has emerged as an effective method for identifying substance and alcohol consumption. Hair traps biomarkers within the fibers of the growing strand, offering a comprehensive history of alcohol and drug use. When collected near the scalp, it provides a detection timeline of up to roughly three months for alcohol and drugs. Hair is easy to collect, challenging to tamper with, and simple to transport.
A 1.5-inch sample, comprised of about 200 hair strands (approximately the width of a #2 pencil), closest to the scalp will yield 100mg of hair, which is the ideal amount for both analysis and confirmation. For EtG, add-on tests, and tests exceeding 10 panels, 150mg of the sample is suggested. It is advisable to weigh the specimen using a jeweler’s scale. If scalp hair is unavailable, an equivalent amount of body hair can be gathered. By "head hair," we mean scalp hair solely, whereas "body hair" includes all other types of hair (such as facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result entails four primary phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial integration of a sample into a laboratory's system. This entails confirming that the sample was appropriately sealed and shipped, allocating a random LAN (Laboratory Accessioning Number), and finalizing any additional data input not furnished by an electronic chain of custody system.
Screening involves a preliminary and rapid evaluation for abusive substances. While Screening is an economical method for ruling out drug usage in most samples, a positive screen must be confirmed for court admissibility. Samples showing presumptive positivity in Screening demand further confirmation.
If a sample registers as presumptively positive during the Screening phase, additional hair is extracted from the original sample for the Extraction process. In this phase, drugs are separated from hair at lower concentrations compared to other techniques (such as urine or oral fluid), rendering hair drug screening one of the most complex methods to execute.
Confirmation for any screening result tested positive is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as required. The entire laboratory sequence from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair accreditation and the ISO / IEC 17025 accreditation standards.
