The urine test strip test for blood is based on hemoglobin's pseudo peroxidase activity in catalysing a reaction between hydrogen peroxide and the chromogen tetramethylbenzidine in order to produce a dark blue oxidation product. [6] [13] the resultant colour can vary between green and dark blue depending on the amount of hemoglobin. [13]
Test for ketonuria using Bayer Ketostix reagent strips. Urine testing is the most common method of testing for ketones. Urine test strips utilize a nitroprusside reaction with acetoacetate to give a semi-quantitative measure based on color change of the strip. Although beta-hydroxybutyrate is the predominant circulating ketone, urine test ...
A urine test strip is compared against a color chart to determine the results. Urine test strips or "dipsticks" allow for the rapid measurement of numerous urine parameters and substances. The strip is dipped into the urine sample and the color changes on the reagent pads are read after a defined period of time, either by eye or using an ...

The pad is allowed to react for an exact, specified amount of time (it is recommended to use a stopwatch to time this exactly and disregard any resultant colour change after the specified time); [3] [4] its resulting colour is then compared to a graded shade chart indicating a detection range from negative presence of ketones up to a ...
β-hydroxybutyrate (the conjugate base of β-hydroxybutyric acid, drawn above) despite chemically containing a carboxylate group instead of a ketone, is the principal "ketone body" in diabetic ketoacidosis. DKA is common in type 1 diabetes as this form of diabetes is associated with an absolute lack of insulin production by the islets of ...
