Blood Test

General
1

I just want to check on what should be included in the initial blood test when trying to diagnose PsA.

So far I’ve come across Rf, ESR, anti CCP antibody, HLA B27

Could someone give me an idea of which what should be tested at this stage

Thanks

They would probably want to do a ANA to rule out SLE Lupus, and mixed connective tissue disease.
