Hair testing has gained recognition as a robust method for identifying drug and alcohol consumption. The hair captures a lengthy history of substance use by embedding biomarkers within the hair fiber as it grows. When the sample is taken near the scalp, it can offer an estimated three-month detection window for drugs and alcohol. Hair collection is straightforward, fairly resistant to tampering, and convenient to transport.
A sample of 1.5 inches consisting of approximately 200 hair strands (comparable to the diameter of a #2 pencil) nearest to the scalp provides 100mg of hair, which is optimal for both screening and confirmation. For EtG, additional analyses, and/or tests exceeding 10 panels, a 150mg specimen is preferred. It's advisable to measure the specimen using a jeweler’s scale. If scalp hair is unattainable, a proportional amount of body hair may be utilized. Reference to head hair implies scalp hair exclusively. Body hair encompasses all other hair forms (facial, axillary, etc.).
Process Overview
The principal stages in the laboratory processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial incorporation of a sample into the laboratory’s system. This step includes validating that the sample was properly sealed and shipped, allotting a random LAN (Laboratory Accessioning Number), and accomplishing any additional data entry absent from an electronic chain of custody system.
Screening entails a preliminary rapid assessment for drugs of abuse. Screening is an economical method for excluding drug usage in most samples; however, a positive screen needs affirmation for court admissibility. Samples with a presumptively positive screen necessitate a secondary confirmation.
If a sample shows a presumptively positive in the Screening stage, more hair is extracted from the initial specimen and readied for Extraction. During this phase, drugs are removed from hair at much lower concentrations compared to other methods (for example, urine or oral fluid), rendering hair drug screening as a challenging method to execute.
Confirmation of any positive screening outcomes is performed via GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptive positive samples undergo washing before confirmation if necessary. The complete laboratory procedure from Accessioning to Confirmation is examined under the CAP (College of American Pathologists) Hair designation alongside ISO / IEC 17025 standards accreditation.
