The GHB EZ Test Kit is designed specifically to detect the presence of GHB (Gamma-Hydroxybutyrate) in a sample and help distinguish it from GBL (Gamma-Butyrolactone). This gives it a more focused application than broader reagent tests, particularly where there is a need to check whether a sample contains GHB rather than similar chemicals that may be confused with it.

When a sample is introduced to the reagent in the ampoule, the test may produce a colour change that can be compared against the included chart to help determine whether GHB is present. A key feature of the kit is that it is designed to show a reaction for GHB while showing no reaction with GBL, helping users distinguish between the two using the supplied colour reference.

Because GBL is used in industrial applications such as cleaning products and is converted to GHB in the body, the ability to differentiate between them is central to the purpose of this kit. The GHB EZ Test Kit is designed to provide a simple visual indication of GHB in a sample, with the included chart supporting straightforward interpretation of the result.
