Blood in urine and abnormal complement
For two years now, I've had trace amounts of blood in my urine, with abdominal discomfort (flank pain, upper-abdominal pain and sore ribs, and a burning sensation down my right side when urinating). I was diagnosed and treated for prostatitis in January 2005. The only tests that have come back abnormal are my urine tests (trace blood, but protein and ketones negative, normal glucose and pH 7), and an abnormal complement (two different complement tests that were low).
I'm emigrating to the US in December and won't have any health insurance for 6 months, so I'm anxious to rule out anything serious while I still have free healthcare.
What could blood in my urine and low complement indicate? Is there anything you would recommend testing for?
