What does it mean to have a possible positive lupus test?

I have been having serious joint pain for some time now. My doctor tested me for arthritis, RA, and lupus. He said the test came back as a possible positive for lupus and he is sending me to a Rheumatologist for further testing. Does this mean they just don’t know or does it mean they are sending me for a confirmation? Has anybody had this happen to them?

Dear Sweat Pea,
the diagnosis of rheumatic diseases and specially systemic lupus erythematosus is based on clinical findings and past medical history. Laboratory values are use mainly for confirmation and sometimes to estimate disease activity. Please be patient until you visit your rheumatologist. As a specialist he will guide you through the differential diagnostic of arthritis (over 200 types!). I’m pretty sure you will feel frustrated after the first visit but afterwards you will begin to built a relationship with your rheumatologist based on his ability to understand your complaints and relieve your pain. Feel free to contact me and ask again!
