Clinical symptoms trump labs. The absence of confirming labs does not mean you do not have lupus...it might. It is not uncommon for lab confirmation to come weeks, months or even years after symptoms occur. In severe cases labs usually do confirm. Get a second opinion but make sure the doc is experienced with lupus.
Hang in there. Many of us have gone through diagnosis hell.
