Hair testing has emerged as a potent method for identifying drug and alcohol consumption. The fibers of the hair strand preserve long-term indicators of substance use, creating a record that can reveal use over several months. When samples are taken near the scalp, they can show drug or alcohol use over a period of up to 90 days. Collecting hair is straightforward, it’s relatively tamper-proof, and easily shipped.
A sample measuring 1.5 inches from approximately 200 hair strands (similar in size to a #2 pencil) is ideal for screening and confirmation, providing 100mg of hair. For tests involving EtG, additional substances, and/or over ten panels, collecting 150mg is advisable. It's best to ascertain the sample weight with a jeweler's scale. If scalp hair isn't available, equivalent body hair can be used. References to head hair specifically address scalp hair, whereas body hair pertains to other types (such as facial or axillary).
Process Overview
The sequence in laboratory processing of drug test results includes Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the entrance of a sample into the laboratory system. This step includes confirming that the sample was sealed correctly and transported properly, allocating a LAN (Laboratory Accessioning Number), and completing any additional data entry that an electronic chain of custody doesn't cover.
Screening is a preliminary check for drugs of abuse. Although Screening is an economical method for dismissing drug use for most samples, a positive indication requires verification for legal acceptability. Samples that test positive in Screening go through further confirmation.
Should a sample yield a presumptive positive during Screening, additional hair from the original sample is extracted for further testing. In the Extraction phase, drugs are extracted from hair at much lower concentrations compared to methods like urine or oral fluid, making hair drug testing one of the most challenging methodologies.
Confirming a presumptive positive from Screening involves analysis via GC/MS, GC/MS/MS, or LC/MS/MS. Preparatory washing of any presumptive positive samples is done as needed before Confirmation. The laboratory process, from Accessioning to Confirmation, is conducted under review by both the CAP (College of American Pathologists) Hair guidelines and the accreditation of ISO / IEC 17025 standards.
