What happens if my urine test show a significant amount of protein up to 217mgm?

Posib. renal disease. First rule out orthostatic proteinuria (only present when up and about) repeat urinalysis first thing in am, after emptying bladder about 2 hrs after going to bed. No concern if am urine is protein free. Otherwise best to consult a nephrologist to rule out & if necessary to treat glomerulonephritis, or nephrotic syndrome if ankle swelling +/or eye-lids puffy.
