Hair testing is increasingly recognized as a robust method for detecting drug and alcohol consumption. Hair captures a long-term record of alcohol and drugs by embedding biomarkers within the hair strand's fibers as it grows. When clipped near the scalp, hair can reflect up to a 3-month timeframe for drug and alcohol detection. Hair sampling is straightforward, challenging to tamper with, and uncomplicated to transport.
A hair sample measuring 1.5 inches and comprising approximately 200 hair strands (comparable to the width of a size #2 pencil) nearest to the scalp yields 100mg of hair, the optimal quantity for analysis and verification. For EtG, additional testing, and panels exceeding 10, a specimen of 150mg is suggested. We recommend using a jeweler's scale to measure the specimen's weight. In the absence of scalp hair, an equal quantity of body hair can be used. "Head hair" specifically means hair from the scalp, while "body hair" includes all other body hair types (facial, axillary, etc.).
Process Overview
The drug testing laboratory process entails four significant stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial integration of a sample into the laboratory's protocol. This step encompasses ensuring the sample's seal and shipment were correct, generating a random LAN (Laboratory Accessioning Number), and completing any additional data entry tasks not managed by an electronic chain of custody system.
Screening serves as an initial rapid assessment for drug usage. Though cost-effective for excluding drug use in most samples, a positive screening must be verified for judicial admissibility. Presumptively positive samples in Screening require subsequent confirmation.
Should a sample test presumptively positive in the Screening phase, additional hair is extracted from the original sample and prepped for Extraction. In this phase, drugs are isolated from hair at lower concentrations compared to alternate methods (e.g., urine or oral fluid), which contributes to the complexity of hair drug screening.
Confirmation of any positive screening is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptively positive samples undergo washing before confirmation if required. The entire lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 accreditation standards.
