Hair testing is perceived as a robust method for identifying drug and alcohol consumption. Hair can provide an extensive historical record by encapsulating biomarkers within the fibers of the developing strand. When taken close to the scalp, the analysis can offer a detection period of nearly three months for alcohol and other drugs. Hair collection is straightforward, hard to tamper with, and easy to transport.
A 1.5-inch segment of around 200 hair strands (roughly a #2 pencil's width) close to the scalp yields 100mg, the optimal amount for analysis. For EtG, additional assessments, or tests beyond 10 panels, a sample of 150mg is preferred. We advise using a jeweler’s scale for weighing the sample. If scalp hair is not present, a similar amount of body hair could be gathered. "Head hair" specifically refers to scalp hair, while "body hair" includes all other types (facial, axillary, etc.).
Process Overview
The drug test result laboratory process involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial stage of entering a sample into the laboratory's system, which includes validating the sample's proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry not submitted through an electronic chain of custody system.
Screening is an initial check for drug abuse. Screening is cost-effective for negating drug use in most samples, but a positive result requires confirmation for court admissibility. Any samples that test presumptively positive during Screening need a subsequent confirmation.
If Screening shows a presumptive positive, more hair from the original sample is prepared for Extraction. In this phase, drugs are extracted from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), making hair drug screening the most complex methodology.
Confirmation of any positive result from screening is conducted utilizing GC/MS, GC/MS/MS, or LC/MS/MS techniques. All presumptive positive samples undergo necessary washing before confirmation. The entirety of the laboratory process from Accessioning to Confirmation is audited under the CAP (College of American Pathologists) Hair standards and accredited to ISO / IEC 17025 standards.
