I had several doctors who tested me year after year and always said I was fine. When I finally tested having both sjogrens & scleroderma I took it to my Primary physician and she: "yes, I knew that but it wasn't that bad"! W H A T? I felt like that was telling a diabetic "oh, yes you have diabetes BUT your sugar level is good today so you're fine!"
If the test shows a specific number, my understanding is, it shows which autoimmune weather flared up or not...we deserve to know either way so we know what to expect when it does flare up.
The great thing now is, mine was flared up by foods that I can easily eliminate, just like a diabetic!
