Thanks for your help, it's greatly appreciated!!!

I guess I need to decide what direction to go from here. If I spend the money on blood tests and they are negative then I will have to come up with more money for the stool tests. I was thinking of having the complete stool test which is around 400 bucks. Ouch!

I guess the first place to start here is to call my insurance company and see what they will cover as part of a physical exam.
