What lab tests for women?

My wife has been slowly gaining weight even with a pretty decent diet and activity level. She feels run down as well over the last couple years. I have mentioned to her that she should get some labs drawn to see where her hormone levels are but I'm not sure what she should check. Any suggestions?
