So I am fairly young, in my 20s and was having brown, tea colored urine (high protein, blood) for over a year. It came out of nowhere, no previous health issues. Got seen by a nephrologist and got bloodwork done, tested positive for ANCA (mpo). Normal kidney function per bloodwork. I started high dose prednisone and underwent a kidney biopsy a month later. However.. the biopsy results came back that there was no evidence of anca vasculitis. A month after the biopsy, my urine was completely clear, no blood or protein.
Has anyone had something similar happen to them? My doctor thought I had some type of mild anca vasculitis that was partially treated by the high prednisone I was taking. Not sure tho, my urine has been clear ever since this but my anca ab continues to be positive.
