Why This Test Might Be Ordered

Your healthcare provider may recommend this test if you have symptoms like frequent urination, pain during urination, blood in urine, unusual urine color, or persistent fatigue. It’s also used as part of routine screening for certain conditions or before certain medical procedures.
