Hair testing is recognized as an effective means for detecting the use of drugs and alcohol. Hair retains a long-term record of these substances by embedding biomarkers in the fibers as the hair grows. When obtained near the scalp, hair can offer a detection period of up to about three months for drugs and alcohol. Hair collection is straightforward, relatively difficult to tamper with, and convenient to transport.
A 1.5-inch hair sample comprising roughly 200 strands (around the size of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal quantity for screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, a specimen amounting to 150mg is advisable. It is recommended to weigh the specimen using a jeweler’s scale. In cases where scalp hair is absent, an equivalent volume of body hair might be gathered. "Head hair" pertains exclusively to scalp hair, while "body hair" encompasses all other hair types (facial, axillary, etc.).
Process Overview
The four principal steps in the lab processing of drug test results are Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into a lab's system. This step includes confirming the sample’s proper sealing and transit, allocating a random LAN (Laboratory Accessioning Number), and performing any supplementary data entry not handled by an electronic chain of custody system.
Screening is a preliminary quick evaluation for substances of abuse. Although it is a cost-effective strategy to negate drug use in most samples, a confirmed positive screen is necessary for legal admittance. Any samples marked as presumptively positive in Screening mandate a secondary confirmation.
If a sample shows presumptive positivity in the Screening phase, additional hair is extracted from the initial sample and prepared for Extraction. During this phase, drugs are pulled from hair at significantly lower concentrations than those in other methods (ex. urine or oral fluid), which makes hair drug testing the most challenging methodology to execute.
Confirmation of any presumptive positive screening outcome is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive specimens are washed before confirmation as appropriate. The full lab process from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
