So I just got a new psychiatrist.  We wanted to do some lab work before adjusting my meds( to see if my fatigue could also be due to something else like thyroid)

So I was just looking at the form he sent and I noticed Rapid Plasma Reagin (RPR).  I was curious and looked it up. The only thing I can find is that its used to detect syphillis.

Has anyone else ever been tested for syphillis by their psych?  I'm wondering what the purpose is. I looked up symptoms and out of about 8 the only one I have is fatigue.
