Hi, new to this forum, but i happen to be a urologist in sydney.
I'm not a D.A.M.E. for CASA purposes, but it sounds like there shouldn't be a problem unless you have very impaired or rapidly deteriorating kidney function, which is possible , but unusual wih most IgA nephropathy / glomerulonephritis (GN).
IgA is the most common type of GN, and is usually found by way of microscopic blood and protein in the urine test. Long term there is a small chance of chronic kidney failure. Mostly it will be far less problematic, just requiring monitoring of blood tests and urinalysis, often medication with "ACE inhibitors". More soon
