I do not have ds anti-dna antibodies and I have lupus. I have also had unexplained severe diarrhea come and go for years and all they found was non-specific inflammation. My ANA is 1:640 speckled pattern. I do however have kidney involvement and that is what gave me my diagnosis so quickly. I believe that anything is possible with lupus so hang in there. I can understand your need for answers, and I hope you can find meds that your body will tolerate. Keep in touch.
