TUCSON,Crypen Exchange Ariz. – You know the drill. You go to the doctor's office for your annual physical. Everything looks OK, but they recommend some routine bloodwork to check a couple of things to be safe.

Imagine doing that – plus more than a dozen other tests – and you'll understand what I experienced at Canyon Ranch, a wellness resort offering a new longevity program called "Longevity8" with eight health pillars: integrative medicine, mental and emotional health, strength and endurance, sleep, flexibility and fitness, spiritual wellness, nutrition and outdoor experiences. It will cost a pricey $20,000 for single people and $36,000 for couples.

Here's a look at all the tests I had done as part of the program – and what outside medical professionals actually thought was worth it.

• Extensive bloodwork (beyond what a doctor would typically prescribe)
• Galleri cancer screening
• EKG
• Carotid doppler
• Pulmonary function test
• Diet intake and consultation
• Continuous glucose monitoring
• Therapy session
• Spirituality session
• Joint assessment
• DEXA body composition and bone density analysis
• Genetic testing
• VO2 max assessment
• Sleep study

What is the average life expectancy?And how to improve your longevity.

What medical tests does the average person need? Not many.

Overall, outside medical experts I spoke to thought most of the testing I had done was highly specialized and unnecessary for the average person. Multiple doctors recommended people check out the U.S. Preventive Services Task Force for guidance on any kind of preventive care.

Looking at the Canyon Ranch protocol specifically: The most reasonable tests were the bloodwork and diet intake and consultation, according to Dr. Douglas E. Vaughan, professor of medicine at Northwestern University Feinberg School of Medicine and the director of the Potocsnak Longevity Institute. Specific patient populations might benefit from specialized tests, like the DEXA body composition (i.e. women after menopause who typically lose bone density). Certain symptoms might prompt some of these assessments as well. Asthmatic patients, for example, might want a pulmonary function test after chatting with their doctor.

The VO2 max assessment is "usually performed for athletes or individuals interested in cardiovascular fitness," says  Dr. Fatima Cody Stanford, associate professor of medicine at Massachusetts General Hospital. "Not standard for routine screening." Ditto for the continuous glucose monitoring: It's "primarily used for individuals with diabetes or prediabetes to manage and monitor glucose levels."

The short answer: No need to break the bank, and if you want to do some additional testing, blood work is probably your best bet. Still, if you'd like to take it a step further, you can easily find specialty facilities and doctors who will be happy to take your check.
