Will results be incorrect if it is outside a certain pH range from the pH optimum of glucose oxidase and peroxidase in the D-Glucose Assay Kit (GOPOD Format) (K-GLUC)?

The test is best run at pH 7.4. The reagent is buffered at this pH. Using different pH values will affect results, i.e. it may take longer to reach this end point; but the same end-point value should be obtained if not too far away from this pH value.
