Hair testing is recognized as a robust tool for monitoring drug and alcohol usage. Hair offers an extended timeline of alcohol and drug consumption by locking biomarkers in the growth fibers of hair strands. Samples cut near the scalp can trace substances up to roughly 3 months prior. Collection is straightforward, it's relatively challenging to tamper with, and easy to send.
A segment of 1.5 inches comprising about 200 hairs (approximately the thickness of a #2 pencil) near the scalp provides 100mg, which is optimal for both screening and confirmation. For EtG, add-ons, or tests exceeding 10 panels, 150mg of hair is suggested. It's best to weigh specimens on a jeweler's scale. If head hair can't be obtained, corresponding body hair may be used. By "head hair," we mean scalp hair exclusively. "Body hair" covers other types (e.g., facial, axillary, etc.).
Process Overview
There are four primary stages in processing a lab drug test result: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the sample's entry into a lab system, verifying seal integrity, proper shipment, assigning an LAN (Laboratory Accessioning Number) randomly, and completing any missing information not captured by an electronic custody protocol.
Screening offers a preliminary evaluation for drugs of abuse. Though a cost-efficient means to negate drug usage for most samples, court submission requires positive screens to undergo confirmation. Samples that are presumptively positive during Screening must receive a follow-up confirmation.
Presumptively positive samples in Screening are supplemented with additional hair from the original sample and readied for Extraction, a phase where drugs are retrieved from hair at lower concentrations relative to other methods (e.g., urine, oral fluid), making hair screening notably complex.
Positive screening confirmations are executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive specimens are pre-washed for confirmation per necessity. The full process from Accessioning to Confirmation is examined under CAP (College of American Pathologists) Hair designation as well as ISO / IEC 17025 accreditation standards.
