Is there a chance that an bladder infection is not detected in the urine test while you have?

Complicated: Urine cultures will occasionally be negative even when infection is present. Urinalysis will rarely be normal in the presence of uti. Sometimes doctors will treat empirically (without proving diagnosis) in women, particularly when they have had UTI previously. You should discuss this at length with your doctor.

Yes: It is often only found after doing a culture of the urine to grow out bacteria.
