Clinistix  Glucose  Test  Strips

Qualitative test for glucose. Pack of 50 Clinistix strips incorporating a reagent area that tests specifically for glucose and changes colour if glucose is present in solution. 

Testing is carried out at room temperature and the colour of the reagent area at 10 seconds after wetting is compared to the colour chart on the bottle label.

Qualitative results are read from the colour chart as negative or varying degrees of positive which indicate the relative amounts of glucose present.  Colour blocks are designated as Negative, Light, Medium or Dark.

Chemical Principles of Procedure

This test is based on a double sequential enzyme reaction.  One enzyme, glucose oxidase, catalyzes the formation of gluconic acid and hydrogen peroxide from the oxidation of glucose.  A second enzyme, peroxidase, catalyzes the reaction of hydrogen peroxide with the chromogen orthotolidine to produce colours ranging from purple through to dark blue.
