Hello,
It would appear that you have a very minimal amount of protein in the urine. Furthermore, it might not actually be real. Because it was a concentration only, it may be falsely elevated by a having a non dilute urine. To clarify this, you should have an albumin (or protein) to creatinine ratio done OR a 24 hr urine to measure the total protein, Once those are performed, you will know if this is even a real finding and how large the quantity is above normal. As well, given the pus cells, you should have a urine culture done as infections can also raise the urinary protein in a spurious way. For now, there is no cause for panic.
