Samples that generate absorbance values A2 – A1 of 0.3 should be diluted in distilled water prior to the Sample Preparation (section A, page 7) and the second incubation of step 2 increased (glucose oxidase / catalase) to 30 min.
In the Lactulose Assay Kit (K-LACTUL) some samples generate values of A2 – A1 greater than 0.3. Is this ok?
