There are a few possibilities, but the most common has to do with the fact that many labs only report a positive urine culture when there is a high level of bacteria growing in the urine, even though low levels can cause symptoms. Next time, ask your health care provider to request a culture that reports any level of growth rather than only >10^5 CFUs. Quest Labs call this "urine culture, special," and Lab Corp calls it "urine culture, comprehensive." It's the same test your health care provider would order for a specimen collected via catheterization. Many health care providers are unaware that the newer tests report only >10^5 CFUs, as they used to report lower levels of growth.

There is no definitive test for lupus. It is possible that some standard tests may come back negative, but the patient does indeed have lupus.

Two negative tests would indicate that you probably are not.
Pregenency tests are not always accurate. The best way to find out is by seeing a doctor, or a proffesional. If you suspect anything, see your doctor even if your tests come out negative.

Maybe. After twelve tests you might want to consider talking to a doctor.
I think you go to the doctor to have a blood test.
