What does mixed urogenital flora 25,000-50,000 colony forming units per ml mean?

In women, this almost always means the urine specimen was not "clean catch" and was contaminated with vaginal bacteria; and does not indicate urinary tract infection. Depending on what symptoms you have and/or what urinalysis shows, your doctor may recommend repeat urine culture. Good luck.

Culture of contaminated urine sample typically results in intermediate numbers of CFU of mixed flora. Another urine culture of specimen obtained by clean catch or catheterized urine specimen from bladder is needed to confirm UTI.
