By substituting glucose with a compound that can be easily noticed with a distinguishable colour change‚ we can then assay for lactose activity.

To determine the effect of pH on the activity of α-amylase the assay will be rum at different pH’s‚ by preparing the sample buffer at different pH’s. The rest of the assay will remain the

its size that is similar to white blood cells (which are often present in specimens taken from patients with a discharge)‚ precautions must be taken to ensure that the observed organism is really motile. The comparison with some newer diagnostic assays shows that wet preparation microscopy is 35 to 60 percent sensitive (even in symptomatic women)‚ which also depends on the expertise of the microscopist. Nevertheless‚ observation of motile Trichomonas vaginalis is highly specific and‚ hence‚ quite
