Hair testing is now recognized as an effective instrument for identifying drug and alcohol consumption. By capturing biomarkers in the fibers of the growing hair strand, hair provides a long-term overview of alcohol and drug use. When taken close to the scalp, hair can offer a detection span of up to three months for alcohol and drugs. It is easy to gather, somewhat resistant to tampering, and simple to send off.
Obtaining a 1.5-inch sample of around 200 hair strands (approximately the width of a #2 pencil) nearest the scalp will yield 100mg of hair, which is the preferred quantity for screening and confirmation. For EtG, additional substances, and/or tests exceeding 10 panels, a 150mg sample is preferred. We recommend utilizing a jeweler’s scale for weighing. Should scalp hair be unavailable, a similar amount of body hair is an alternative. When referring to head hair, we mean scalp hair exclusively. Body hair encompasses other types of hair (facial, axillary, and so on).
Process Overview
The key phases in the lab procedure of processing a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning addresses the initial sample intake into the laboratory system. This involves checking that the sample was sealed and sent correctly, allocating a random LAN (Laboratory Accessioning Number), and carrying out any other necessary data input not covered by an electronic chain of custody system.
Screening is a preliminary assessment for drugs of abuse. While Screening is a budget-friendly method to eliminate drug use in the majority of samples, a positive screen needs verification for court admissibility. Samples that are presumably positive in Screening require further confirmation.
If a sample shows a presumptively positive result in the Screening phase, extra hair is extracted from the initial sample for Extraction. During this phase, drugs are extracted from hair at much lower concentrations compared to other methods (such as urine or oral fluid), making hair drug screening one of the most challenging methods to execute.
Confirmation of a positive screening outcome is conducted through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing as necessary before confirmation. The entire laboratory protocol, from Accessioning to Confirmation, is evaluated under the CAP (College of American Pathologists) Hair designation and bears accreditation under ISO / IEC 17025 standards.
