Blood Testing Panel

I was looking at the different blood test panels on LifeExtension (lef.org) and was wondering if any of you guys could help me with what are the important tests to look for in a panel.

I do not use anabolic steroids. I am just curious as to what my currents levels are since I have never had one done before.

Would a basic male hormone panel be fine with just:
Estradiol (an estrogen)
Free and Total Testosterone

Or would a more comprehensive panel be worth the extra cost?
