Hello Doctor . Two months ago I had pain in my right leg including knee, I did the test of RA factor, Vitamin D and calcium all are normal, then some told me to get the test of Urine DR, my results are Hemoglobin ((Small+), RED BLOOD CELLS 4/HPF , LEUKOCYTES 3/HPF. BACTERIA Moderate, Calcium OXALATE CRYST FEW and MUCUS +1, all other values are normal, what does it means?
