Hair testing is now widely recognized as a potent means for identifying drug and alcohol consumption. Hair retains markers of these substances in the fibers of the developing strand, offering extensive historical insight. When obtained near the scalp, it allows for a detection timeframe that can extend to roughly three months. Hair collection is straightforward, relatively resistant to tampering, and conveniently shipped.
An optimal sample, approximating 1.5 inches and involving about 200 hair strands akin to the diameter of a #2 pencil, equates to 100mg, which suffices for screening and confirmation. For EtG, add-ons, or panels above ten, 150mg is advised. Using a jeweler's scale for specimen measurement is recommended. If scalp hair is unavailable, an equivalent amount of body hair can be used. "Head hair" pertains only to scalp hair, while "body hair" encompasses all other hair types, including facial and axillary.
Process Overview
In the lab, a drug test result proceeds through four steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning begins with the sample's initial entry into the lab's system, ensuring the sample’s seal and shipment is intact, assigning a random Laboratory Accessioning Number (LAN), and completing data entry absent in an electronic chain of custody.
Screening offers a rapid check for substances. Though cost-effective for ruling out drugs in most specimens, a positive screen mandates confirmation for legal admissibility, requiring any presumptively positive samples to undergo confirmation.
For samples testing presumptively positive, further hair is extracted from the original specimen for the Extraction phase. Here, drugs are drawn from the hair at significantly reduced concentrations compared to urine or oral fluid, underscoring the complexity of conducting hair drug tests.
Confirmation for positive screenings deploys GC/MS, GC/MS/MS, or LC/MS/MS. Samples indicated as presumptively positive undergo necessary pre-confirmation washing. The full process, from Accessioning to Confirmation, adheres to both the College of American Pathologists Hair designation and ISO / IEC 17025 standards.
