Ketostix 2

Ketostix measure urine ketones.

Ketodiastix 300

Ketodiastix measure both urine glucose and urine ketones.


Because most urine tests measure acetoacetic acid, and not the most commonly found beta-hydroxybutyrate acid, it is possible to have ketones present and get a negative urine test result.

Further, it's also possible to have high levels of beta-hydroxybutyrate acid, get a negative urine ketone test result, but to have the test turn positive as the ketosis improves, due to the tests' measuring acetoacetic acid and not beta-hydroxybutyrate acid. [1]

The following medications and/or problems with urine samples can produce false negative or false postive results when testing urine for ketones.

See Urine testing stix-Reading Results for examples of ketodiastix and ketostix color charts.


If your pet is taking any type of vitamin supplements, it should be noted on his or her medical records. Knowing that he/she is using them means being able to factor them into interpretations of test results.
