Core, essential and when-indicated tests.

Core measures are the ones your Kodo Score™ is built from. Essential tests don't change the score, but they confirm what your physician needs to know before writing your plan. When-indicated tests are ordered only when your history or results call for them.

Personalized by your physician

Your exact tests depend on your history, goals and past results. Not everyone needs every test, and some are added only when they would change your plan.

Where testing happens

Most blood work is a single local draw, and imaging and fitness tests are arranged near you. Labs and imaging are billed separately.

This catalog is educational and is not medical advice. Test availability can vary by location, and your physician decides what is appropriate for you.
