Ketones and glucose in urine can be a confusing combination. Both substances are produced by the body and are harmless, although high levels can indicate a serious medical condition. While small levels of glucose and ketones in urine are not dangerous, large amounts of both are a sign of a condition called diabetes mellitus or metabolic acidosis. While high levels of ketones in urine may not be life-threatening, they should be taken seriously.
If you have elevated blood sugar, you should be worried. Ketones are produced when the body uses fat as a fuel source. In diabetics, this fuel source causes the body to burn fat instead of glucose. This results in ketones in the blood. These substances spill into the urine and are toxic to the body. If you're concerned about high levels of ketones, you should contact your healthcare provider immediately.
If you're concerned about the elevated level of ketones in your urine, you should visit a doctor. This test can be performed at home or in a laboratory. You'll need to clean your genital region thoroughly. Then, you'll need a collection container that you can place under the stream of urine. The urine must be returned to your health care provider as instructed.
