I have been noticing sediment/white stuff in my urine for about 6 weeks now. I had a blood test in September testing for kidney function, which came back fine. 4 weeks ago I visited my GP and did a urine sample, it was dip sticked it indicated a very small trace of protein. However when it was sent away to be looked at by a laboratory It came back fine and everything was in its normal range. My GP has told me as the urine and blood samples are normal, everything is fine. But I still keep seeing this white sediment. Should I be worried?
