My baby is 55 days old right now. So, after his jaundice, the doctor asked for a urine culture. The urine culture test was performed to test for positive results with a count of 50,000. The doctor has given an antibiotic for 10 days. Then the culture test was negative again after 10 days he asked for a culture again. It was coming positive with a 20,000 count. But now the doctor is asking not to worry. Everything is okay. It will go on its own.Is their anything to worry??
