I'm sorry to hear that your daughter is experiencing urinary symptoms. Based upon her symptoms, the positive urine dip test, and the contaminated culture, she most likely has a UTI. Contamination of the urine culture with skin bacteria, makes the culture less accurate. Because of the presence of skin bacteria, often the lab cannot detect the infectious bacteria that is causing the symptoms. So, in her case, it's best to complete a course of antibiotics as a precaution.

This situation is not uncommon, as 20% of culture are contaminated and therefore inaccurate. I hope she feels better soon.

the culture is wrong? i should continue with her antibiotics even though the her dr told me to stop taking no sign of bacteria ?
Expert:  Dr. Greg replied 9 days ago.

There was detectable contamination. The ability of the culture to detect other infectious bacteria in the setting of contamination is limited. So, the culture could not specifically identify the bacteria causing the infection. Yet, her clinical symptoms are consistent with an infection. I would recommend that you complete the course of antibiotics, as a precaution. The culture should be interpreted as "inconclusive", not "negative" when there is contamination.
