Hair screening is now regarded as a potent method to identify drug and alcohol consumption. Hair captures a long-term record of substances by embedding biomarkers within the fibers of the growing hair shaft. When collected near the scalp, hair can offer a detection timeframe for alcohol and drugs of up to around 3 months. Hair is effortless to gather, relatively challenging to tamper with, and simple to transport.
A sample of 1.5 inches consisting of approximately 200 hair fibers (roughly the size of a #2 pencil) nearest to the scalp will yield 100mg of hair, the optimal sample for analysis and verification. For EtG, add-ons, and/or checks exceeding 10 panels, 150mg of the sample is advised. It's recommended to weigh the sample on a jeweler’s scale. If scalp hair isn't accessible, a similar quantity of body hair may be used. When discussing head hair, we specifically mean scalp hair. Body hair covers all other types (facial, axillary, etc.).
Process Summary
The four primary steps included in processing a drug test in the lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning deals with the initial integration of a sample into a lab’s framework. This step involves confirming that the sample was correctly sealed and shipped, generating a random LAN (Laboratory Accessioning Number), and completing any additional data entry that isn't covered by an electronic chain of custody system.
Screening consists of an initial rapid examination for substances of abuse. While Screening is an efficient method to eliminate drug use in most samples, a positive result must be confirmed to be permissible in court. Any samples that exhibit presumptive positivity during Screening need further confirmation.
If a sample shows presumptive positivity at the Screening phase, additional hair is extracted from the original sample and prepared for Extraction. In this phase, substances are isolated from hair at a much lower concentration than with other methods (e.g., urine or oral fluid), making hair drug screening the most complex methodology to conduct.
Any positive screening outcome is verified through GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptive positive samples are cleansed prior to confirmation as necessary. The comprehensive lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
