I have had many blood test in the past few years but everything comes back negative. Even when all symptoms and physical abnormalities fit and the doctors are sure I will test positive, the results are still negative. E.G. if I eat potatoes, I get an anaphylactic shock but the skin-scratch-tests were negative for any allergies.
Only ferritin is immeasurably low.
Now I am being tested for Lupus, and although my rheumy is almost 100% sure it will be positive, I can't put my hopes for it and I am sure it will be negative once again.
Has anyone else experienced this? Why is it, all blood-tests come back normally? Could any disease cause this?
I'm beginning to think I might be a hypochondria, even though I have so many physical complications.
