hormone test: blood vs. saliva?

I'm seeing my primary tomorrow to ask about blood testing for RA and other immune factors. (Probably everything will come back normal but at 11 months post I feel the need to try SOMETHING.) My question about hormones is, have you found the saliva testing to be more accurate? I am having more menopausal symptoms now than I was with Mirena in, but my blood estrogen was ok. I heard saliva was better but it costs $250. Is it worth asking about it tomorrow? I am only 36.
