Testsealabs GHB Gamma-Hydroxybutyrate Test
Gamma-hydroxybutyric acid (GHB) is a colorless, odorless chemical and has become one of the most dangerous illicit drugs of abuse today. It has gained notoriety as one of the "date rape" drugs, and there is a growing trend of its use as a recreational drug.
Manufactured lots of GHB test devices were evaluated for sensitivity, assay response range, cross-reactivity, precision, and stability. Specifically, the lowest and highest ranges of detectable response were determined. The precision of the assay response across different device lots was also examined. Additionally, the influence of common urine interferants and compounds with similar chemical structures was assessed. The stability of the device response after exposure to high temperatures and moisture—both inside and outside the original packaging—was also investigated.
The devices demonstrated good precision. Within-lot precision was maintained within a color scale unit (based on the IDS color chart) across different days and between storage containers. The GHB Gamma-Hydroxybutyrate Test (Urine) is a visually interpreted test.
