Hi folks. I am currently in the process of getting diagnosed. Right now they are leaning towards a lupus diagnosis but it is not certain yet since I do not have most of the common symptoms. The only real symptom I have is systemic inflammation of tendons all over my body. I also have unspecified thyroiditis (tested negative for Hashimoto's antibodies, but thyroid is inflamed on ultrasound and I need meds for it). The tendon problems got severe in the past, then seemed to pretty much go away for a couple years at the same time I got diagnosed with hypothyroidism, then came back recently.
In terms of lab tests, I have had normal or elevated ESR, and I have tested negative for Lyme disease, HLA-B27, RF, and hemochromatosis. My first ANA test was negative several years ago, and a recent ANA test from a new doctor came back negative but just barely negative. He ordered some other tests based on the borderline ANA result, and these are the ones I need help with.
My lab results were:
SM/RNP IgG Ab positive
RNP IgG negative
SSA (Ro) Ab IgG negative
SSB (La) Ab IgG positive
I've been trying to look up what this means but I'm pretty confused.
It sounds like testing positive for Anti-Sm means that I probably have lupus? My rheumatologist is going to put me on a 25 day tapering prednisone course to see if it helps, and I guess is going to try to diagnose me based on whether or not the prednisone helps anything. I am currently taking Lyrica and Tylenol to reduce the pain level.
Have any of you seen labs like this before? Do you know what they mean? I could use all the help I could get! Thanks!
