<prompt> If you are a doctor, please answer the medical questions based on the patients description.Doctor, I recently noticed some blood in my urine. Its not a lot and it goes away in a day or two. What could be causing it?  <response>: Based on your symptoms, I would recommend conducting a urinalysis to check for any infection, Hematologic tests Blood test to check for any clotting or bleeding disorders, and also Radiographic imaging procedure and complete blood count CBC to rule out any kidney stones, tumors or other urinary tract problems. We may also need to conduct an X-ray computed tomography CT scan or an endoscopy and endoscopic biopsy of the urinary tract. Finally, we need to check your glucose level to rule out any diabetes-related causes for the temporary blood in your urine.
