Any definitive tests (blood or radio graphic) to show that you have spondylarthritis?

Not really ... In the link that follows, scroll down to the subtitle "AXIAL AND PERIPHERAL SPONDYLOARTHRITIS DIAGNOSIS"

https://www.uptodate.com/contents/axial-spondyloarthritis-including-ankylosing-spondylitis-beyond-the-basics/print#:~:text=Ultimately%2C%20the%20diagnosis%20of%20axial,magnetic%20resonance%20imaging%20(MRI).

The problem with PMR and spondyloarthritis is that nothing is a specific finding that can be used to confirm either one. MRI is a useful diagnostic tool. Unfortunately, for our generation MRI wasn't used very often. A diagnosis was usually made based on the "preponderance of the evidence" which is greater than a 50% chance but that isn't definitive.
