Test Limitations:

Test Limitation: False negative results are due, in part, to interfering substances, diluted urine, low urine pH and subjective interpretation of the criteria for further workup of the culture. • Genital infections may present similar signs and symptoms of a UTI. Tests to rule out N. gonorrhoeae, Chlamydia and other agents of sexually transmitted diseases must be considered. In addition, agents of vaginitis and vaginosis must be included such as Gardnerella vaginalis, C. albicans, yeasts and Trichomonas. • UTIs have a 25% chance of recurring regardless of antibiotic intervention.
