Without history any recommendations for asymptomatic testing is just plain silly IMO.
Usually it just leads to stress or worse... intervention for a perceived outlier test that is simply not pathological in the individual sense, but is still seen as outside of "normal" range.
Ok, now that I got that off my chest. Vitamin D is a safe one to get. I'd not do a full thyroid panel unless you are symptomatic or have other tests that come in highly irregular.
The real questions are what is your health history and are you symptomatic in any way that you feel you need testing?
