Urine Samples to Monitor Diabetic Dogs and Cats
Testing urine of diabetic dogs and cats can be used to look for:
- Hyperglycaemia in a stable diabetic patient
- Ketones
- Recurrent hypoglycaemia
Glucosuria reflects hyperglycaemia in the past and does not indicate the current status or reflect hypoglycaemia. Glucosuria is not a very reliable method of monitoring diabetes mellitus and should not be used on its own to adjust an animal's insulin dose.
Hyperglycaemia
Urine monitoring can be used once an animal is known to have blood glucose concentrations in an acceptable range. In this case it is a quick easy method of detecting hyperglycaemia. This should then be investigated further by measuring

glucose concentrations.
Ketones
Urine monitoring is a
quick and easy method of detecting ketones (ketonuria) and hence
a potential emergency situation. See

ketoacidosis.
Hypoglycaemia
In diabetic dogs that are well controlled
the urine should be free of glucose for most of each 24 hour period.
Monitoring of urine for
glucose can be useful in diabetic dogs that are not yet stable and
that have problems with recurrent hypoglycaemia. Here it is used
to identify the absence of glucose. For example, a dog that has
no glucose in morning samples may be at risk of hypoglycaemia.
