Hello and Welcome to our WHL family. While there is no one test that can diagnose Lupus, there are a battery of tests that, when looked at cumulatively, can allow doctors to deduce (after eliminating other possibilities) that there is an Auto-Immune/Connective Tissue issue occurring and that the issue could very well be Lupus.
Most of us do not get a concrete diagnosis for years! As I've mentioned, diagnosis is really a process of elimination as there are over 60 Auto-Immune disorders and many of the symptoms are the same. Because of the nature of the disease (flare ups/diminishing symptoms/worsening symptoms/appearance of new symptoms), our test results can be positive at one reading and negative at another. The disease changes in each of us for varied reasons and as it does, our lab results will also change. So, it is never a good idea to make a diagnosis (or deny a diagnosis) based purely upon test results at any given time.
I say all of this to say that there is no way to give you a yes or no answer to your question; I am sorry. It appears, however, that your doctors are treating you for your symptoms and that a diagnosis, at this point, is being used to provide you with the best course of action in order to allay some of your symptoms.
I wish you the very best and please feel free to ask us any questions that you may have, we are here to help you as much as we can.
Peace and Blessings
Look For The Good and Praise It!
