Hi doc, My name is Ganesh.....i am a working professional...as per company policy, i had undergone periodic medical examination.....in urine tests, i got to know that there are traces of occult blood, 5-7 RBC and bacteria in my urine......please let me know, is that harmful? Should i get treated for that? What are the treatments? Why does that happen so i can be cautious in future. Pls help.
