My doctor required a physical, which included complete blood work and an EKG, but nothing more for me. I think the results of the blood tests determine what else might be needed for many people. The psych consult is standard for insurance coverage (and many docs require it even if one is self-pay), and a nutritional consult is also very, very common.
Other than those things, I think doctors make testing decisions mostly based on the patient's health and history. Well, American doctors, anyway.
