Human and animal diabetics both use ketostix or ketodiastix. These are reagent indicator strips that test urine for only ketone (ketostix) or for both ketones and glucose (ketodiastix). These links show examples of Ketostix and Ketodiastix. These stix are available at any brick-and-mortar or Internet pharmacy that sells human diabetic supplies. Stix do expire, so check the unopened expiration date when you buy them and record the date you open them. Keep the bottle tightly closed when not in use; prolonged exposure to air can produce false negative urine ketone test results.
