Hair testing is now recognized as an effective method for detecting drug and alcohol usage. Hair captures a long-term history of alcohol and other substances by embedding biomarkers within the fibers of the growing strand. When collected close to the scalp, hair provides an approximate 3-month detection period for alcohol and drugs. Hair collection is straightforward, somewhat challenging to tamper with, and simple to transport.
A sample of 1.5 inches comprising roughly 200 hair strands (approximately the size of a #2 pencil) close to the scalp yields 100mg of hair, which is optimal for screening and confirmation. When conducting EtG, add-ons, and/or tests exceeding 10 panels, a 150mg sample is advisable. It is recommended to weigh the specimen using a jeweler’s scale. If scalp hair is not accessible, a comparable amount of body hair can be obtained. In discussions of head hair, only scalp hair is considered. Body hair pertains to all other types (e.g., facial, axillary).
Process Overview
The primary steps in the lab processing of drug tests include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial procedure of introducing a sample into the lab system. This step includes ensuring the sample was sealed and dispatched correctly, assigning a random LAN (Laboratory Accessioning Number), and finalizing any extra data input not available via an electronic chain of custody system.
Screening consists of a quick initial check for drug abuse. While Screening is a cost-effective measure to exclude drug usage in most samples, a positive screen needs official confirmation for legal admissibility. Presumptive positive samples in Screening require a secondary confirmation.
In cases where a sample is deemed presumptively positive during Screening, additional hair is extracted from the initial specimen and prepared for Extraction. Here, drugs are retrieved from hair at lower concentrations than other methods (e.g., urine or oral fluid), which underscores the complexity of hair drug screening as a method.
Confirmation of any positive screen is achieved through GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing prior to needed confirmation. The entire lab process from Accessioning to Confirmation is examined under CAP (College of American Pathologists) Hair designation and is accredited to ISO / IEC 17025 standards.
