Hi DiggityDave. I guess the most important thing to say is that there is not one blood test for systemic lupus. To diagnose lupus you must meet 4 of 11 set criteria. Please click on Lupus Resources at the top of our forum and go to AlwaysRosie's post for the link to lupus.org.
Besides systemic lupus, which can effect the entire body, there is also discoid lupus that effects the skin, and drug induced lupus.
No doubt the receptionist at your new doctor was skeptical because so many folks think they have lupus, but don't meet the criteria.
I have major depressive disorder and take 5 psych drugs, but I've only had it for about 7 years. Sadly, it took 2 years for me to get diagnosed with lupus because I was in a new town and didn't have a doc who knew me well. So docs thought that since I was depressed the symptoms were psychosomatic. I had to go doctor hopping. Finally one of my tests was positive and I was referred to a rheumatologist. It was another year before I met 4 lupus criteria and was diagnosed.
Yes, it was a great relief to know what was causing all my problems.
I guess the most important thing is to try your very hardest not to stay calm and take Lynnette's advice and stay with a doc you have a relationship with. Love, Butterflake
