Today my rheumatologist said I am negative for HLA-B27 done by a previous doctor who also found me positive for R.A. factor. This rheumotologist redid the R.A. test which came out negative with his lab(U. of Wash.)after a positive from previous lab, but trusted previous lab's tests for HLA-B27 which came out negative. I also asked for an x-ray to see if my spine had fused and he said only if the physical therapy does not work. He did, however, give me blood work for kidney and liver function as I am on diclofenac which I thought was a good precaution. i am just wondering, for those who have been diagnosed with spondylitis, what tests do your rheumotoligists give you before the diagnosis and expecially to see if it is ankylosing spondylisis?
