Hi Stef and welcome to WHL! We are so glad that you found us! Although I don't want to alarm you I will tell you that blood work in Lupus patients fluctuates. That is one of the reasons that many Lupus patients have a hard time getting diagnosed. Sometimes the meds will get them under control, sometimes a period of remission or a less active period will allow them to return to normal but Lupus itself doesn't simply go away.
There is no need to panic though. If you have been in a period of remission for 18 years then most likely they will be able to get yours back under control. I would like to say that I am shocked that the doctor didn't do an ANA test but I am seldom shocked by doctors anymore. Try to relax (I know, easier said then done) and wait for the test results. As you most likely know if it is Lupus stress will only make it worse. The good news is that you have found us now and we will be here for you if you need a place to vent, talk, laugh or cry.
