3 urine specimen should reduction in RBC from +2 to negative over month. Protein increased from +1 to +2 in the last one. Why protein increased?

Resee MD. You may have some underlying kidney issue that needs attention with prior red cells and now increasing protein in your urine. Please be checked properly and make sure blood pressure is checked as well as blood tests are requested if your doctor deems this indicated. Certainly follow-up urines are needed to follow protein and evidence of red cells. Good luck.
