Hair assessments are regarded as a robust method for identifying drug and alcohol consumption. By capturing biomarkers within the strands, hair yields a prolonged history of alcohol and drug use. When clipped near the scalp, hair can offer an approximate detection period of three months for alcohol and drugs. This method is easy to conduct, challenging to tamper with, and straightforward to transport.
An ideal screening and confirmation sample consists of a 1.5-inch segment of roughly 200 hair strands (the thickness of a #2 pencil) nearest to the scalp, amounting to 100mg. For EtG, additional analysis, and/or tests exceeding 10 panels, it’s advisable to use 150mg of the sample. Utilizing a jeweler's scale to weigh the specimen is suggested. Should scalp hair be absent, a similar quantity of body hair might be used. References to head hair specifically mean scalp hair, whereas body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The lab processing of a drug test result includes four major steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the onset of sample integration into a laboratory’s system, which encompasses ensuring proper sealing and shipment of the sample, assigning a unique LAN (Laboratory Accessioning Number), and completing supplementary data entry absent from an electronic chain of custody system.
Screening offers an introductory rapid assessment for substances of abuse. While Screening effectively rules out drug usage for a majority of samples, any positive findings necessitate confirmation for validity in legal proceedings. Presumptively positive results require additional confirmation.
Should a sample be deemed presumptively positive in Screening, extra hair is extracted from the primary specimen and readied for Extraction. During this phase, drug extraction from hair occurs at concentrations lower than other testing approaches (e.g., urine or oral fluid), highlighting the complexity of hair drug screening procedures.
Confirmation of any positive Screening outcome is accomplished via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo a washing process prior to confirmation if required. The entire lab workflow from Accessioning to Confirmation is scrutinized according to the CAP (College of American Pathologists) Hair designation and accreditation under ISO / IEC 17025 standards.
