This study focuses on patients who have microscopic (non-visible) blood in their urine, which may be an early sign of bladder cancer. The purpose of the study is to determine whether an investigational laboratory test can detect bladder cancer in urine. To evaluate the test’s effectiveness, researchers will collect samples of urine and any bladder tissue (if available), along with information about the participant’s condition.
