Welcome to our group, I'm glad you joined us. I am one of those people who has at least 4 of the 11 criteria, but other than a postivie ANA all my other lupus labs come back normal. I was given a quick diagnosis though because I have kidney involvement and lupus nephritis showed up on my kidney biopsy. I also have a wonderful nephrologist and rheumatologist, both of whom realized I did have lupus even though my labs didn't indicate it. Most people with kidney involvement have anti-DSDNA but I do not. So to answer your question, yes you can have lupus even without positive labs. Feel free to ask any questions, we answer the best we can and there are no dumb questions. Hope your stomach is feeling better.
