An ultrasound with the proper equipment and proper staff is one of better choices for arthritis. I say this in caution - roughly 15% that properly trained by experts fail at ultrasound. There are two blood test CRP and ESR. CRP test short term inflammation, while ESR is long term inflammation. All three together is good as gets for a diagnosis.
You also may want to look for "pencil in the cup." Damage in the fingers from PsA tends to look like this. A decent rheumatologist can guess it from feeling the hands and using imaging to back it up.
