docs will do a blood chemistry (na, k, cl, co2, bun, cr) and blood count (wbc, hgb, hct, plt). ask about fasting blood sugar and cholesterol. as mentioned, vit. D is worth getting as well, if you aren't taking any supps or getting frequent sun. your doc will likely raise his/her eyebrows about doing a testosterone level but you can get that too.
that along with a blood pressure reading should do it.
