This test is used to find the cause of – or monitor – urinary tract infections, bleeding in the urinary system, or kidney or liver disease. It can also be used for diabetes, some diseases of the blood, and bladder stones.
This test measures blood glucose regardless of last meal. Several random measurements may be taken throughout the day. Random testing is useful because glucose levels in healthy people do not vary widely throughout the day. Blood glucose levels that vary widely are indicative of problems like diabetes.
