I usually have semi-formed stools my doctor asked me to undergo Stool test and Urine DR. Stool test report shows: stool consistency: semi-formed, WBC: Occasional/hpf, RBC: Nill, Ova, parasite & cysts: not seen. Urine DR shows: WBC: Occasional, Nitrites: Positive, RBC: Nill, Bacteria: ++. I am extremly worrid is it something serious?
