I was wondering if anyone could suggest what blood work I could have done to see if my body was deficient in any areas.
Ask your doctor.
I agree with Crickster. If you tell your doctor what you are doing, he/she will be able to give you a full lineup of tests to make sure all is well.
A Naturopath may be more comprehensive—occasionally you can find one who is also an MD and everything gets covered by your insurance. Always a good idea to run a candida blood test. You can use the level to compare in the future.
