I like your immunologist! One thing about medical tests that is important to consider - does knowing the results of your test change what you would do? Otherwise the test is pointless. So would you eat differently or take a statin or exercise more if you knew your cholesterol was high? I wouldn't.
A good publication is deLongeril's critique of the JUPITER trial from the Archives of Internal Medicine from earlier this year. I would link it but I'm on my iPhone.
