Abstract
A method for determining the presence or amount of gamma-hydroxybutyrate or precursors in a sample, said method comprising contacting said sample with an indicator which specifically binds to gamma-hydroxybutyrate or precursors to form an indicatorcomplex; and, measuring said indicatorcomplex to determine the presence or amount of said gamma-hydroxybutyrate or precursors in said sample.

A method for quantitatively determining gamma hydroxybutyrate comprising:
- contacting a sample with the mixture of an esterase, a pH indicator dye and a buffer;
- determining a color change in the mixture and correlating a color change with the amount of GHB in the sample.
A method for quantitatively determining gamma hydroxybutyrate comprising:
- contacting a sample with the mixture of an enzyme conjugated to GHB-antibody, enzyme substrate, and a buffer;
- determining a color change in the mixture;
- and correlating the color change in the mixture with the amount of GHB in the sample.
