Hair testing is widely recognized as an effective method for identifying substance use including drugs and alcohol. Hair can reveal extended usage patterns by trapping markers in the strands as it grows. When cut close to the scalp, hair shows a detection period for alcohol and drugs of up to roughly three months. It’s effortless to collect, relatively resistant to adulteration, and straightforward to transport.
Collecting a 1.5-inch sample of roughly 200 hairs (similar in thickness to a #2 pencil) from the scalp yields 100mg, optimal for screening and confirmation purposes. For EtG, add-ons, or tests over 10 panels, a 150mg amount is suggested. We advise using a jeweler's scale for measuring the specimen. If scalp hair isn’t accessible, a comparable amount of body hair is an option. When discussing head hair, we mean only scalp hair while body hair applies to any other types (e.g., facial, axillary).
Process Overview
The key procedural steps in processing a lab drug test result encompass Accessioning, Screening, Extraction, and Confirmation.
Accessioning starts with entering a sample into a lab’s system, checking for proper sealing and shipping, assigning a LAN (Laboratory Accessioning Number), and inputting any missing data not supplied by an electronic chain of custody.
Screening involves a preliminary check for substance abuse. Although cost-effective at eliminating the majority of samples, a positive screen result requires confirmation for legal validity. A secondary confirmation is necessary for any presumptively positive samples.
A sample considered presumptively positive in Screening leads to more hair being drawn from the original sample for Extraction. Here, hair is extracted at much lower concentrations than other methods (such as urine or oral fluid), contributing to the complexity of hair drug screening.
Confirmation of any positive results from screening is executed via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are washed as necessary before confirmation. The entire process from Accessioning to Confirmation undergoes review following both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
