Recently about 20 days ago I got trace protein in urine and then I again got cue done after 10 days and it said nill proteins but there's a lot difference in my specific gravity of sample can it be a possibility that I have given a dilute sample and hence proteins weren't detected ..my pc Ratio and acr are in normal limits but when I check with dipstick that I have at home it shows trace protein can't understand if should not be worried or be concerned and get further testing done
