Hello,I had my son, age 9, take an AVO uti home test, and it showed negative for nitrates and positive for leukocytes. His only symptom is back pain on lower left side which has been going on for a couple of weeks. I ignored it because I thought it was a pulled muscle since it only hurts when he runs.  However, in the past his urine has been cloudy on occasion. No pain during urination and no fever.  We are out of town and I am concerned.  Should I find a doctor?  What could this indicate?  Could it be a kidney infection?
Hello Carol, Welcome at Chat Doctor. I have read your complete question. The presence of leukocytes in urine which are more than 5-10 /high power field or significant is found in kidney or bladder infection in maximum no. of cases. In this it will be best in favor of child to get culture of urine done. It will indicate you the culprit behind his symptoms. This will also help you to give you pinpoint name of antibiotic which should be started for his complete recovery. Hope this will help you. With best wishes.
