Hi,
How are you? The presence of protein in urine (
proteinuria) is due to failure of kidney to filter the body fluids. This can occur due to infections to the kidney, hypertension, diabetes, autoimmune diseases, nephrotic syndrome etc. Although a single measure of protein in a urine sample has less significance. I would suggest that you get a 24 hour urine collection and estimation of protein in that. This is a reliable method to assess the condition.
