What is it used for?A ketones in blood test is mostly used to check for diabetic ketoacidosis (DKA) in people with diabetes. DKA can affect anyone with diabetes, but it is most common for people with type 1 diabetes. If you have type 1 diabetes, your body does not make any insulin, the hormone that controls the amount of glucose in your blood. People with type 2 diabetes can make insulin, but their bodies don't use it properly.
