Is it normal for protein to fluctuate in IgA neuropathy?

Hi doctor,

I was diagnosed with early IgA nephropathy, about five years ago, and I am on medication. Protein and blood are present in the urine, and their levels have varied over time, ranging from traces to ++. My recent urine analysis showed protein (+), erythrocytes (++), RBC (8-10 /HPF), creatinine (1.2 mg/dL), and eGFR (67). Does the fluctuating levels of protein and blood, present in the urine sample considered normal, given that I have been diagnosed with early IgA and undergoing medication? My concern is that the levels tend to fluctuate with every test (which is usually conducted at six monthly intervals). Your advice and views are appreciated.

Thank you doctor,

The biopsy was done, and it was diagnosed as mesangial proliferative glomerulonephritis or early IgA nephropathy. My BP is under control and is 125/80 mmHg. I take Cardace 10 mg and Minipress 2.5 mg as medication. And I also take Statins 10 mg for cholesterol. My microalbumin in spot urine was 143 mg/L with an ACR of 178 mg/g in my recent test. This is more or less in line with past trends over the years, although it suddenly spiked to 459 mg/L two years back, at that time my BP medication was increased. My creatinine has been at 1.2 mg/dL for the last three years. I usually do a spot microalbumin test. I also have a benign enlarged prostate problem, but I do not take any medications at present. My PSA total was 1.04 ng/mL and free PSA was 0.28, in the recent test. I also had a sore throat (mucus and irritation but no fever) three days before and during my recent blood and urine test. Would the benign enlarged prostate and sore throat have also contributed to the sudden increase in RBC?
