A ketone test can alert you to diabetic ketoacidosis, a dangerous consequence of diabetes (DKA). Any of a group of organic compounds (including acetone) with a carbonyl group linked to two carbon atoms are referred to as KETONES. A medical emergency known as diabetic ketoacidosis (DKA) is brought on by serious complications from diabetes mellitus. As insulin levels fall, glucose in the bloodstream cannot enter the body's cells and tissues, which results in diabetes mellitus.
