Urine analysis indicated RBC level of 64.3. Hemoglobin result was Large. No infection was indicated. I am male, age 67. Very active (tennis, resistance training, swimming). I also to sets of vertical jumps, but feel that I land softly. Scheduled for ultrasound of the kidneys this week. Statistically, what are the chances urine blood levels are due to cancer? I take 20 grams of whey protein 3-4 times per week.
