Thanks for posting this. I was able to plug in all the required values from my last checkup and blood work. Even EGFR was there, I've never paid attention to that before.

I learned about it on the Barbell Medicine podcast! They had an episode dedicated to it.

Highly recommended to search their episodes for anything about health or fitness you've been curious about.

Nice, I just subscribed to their podcast. I'm an adherent to the Starting Strength / Mark Rippetoe school of thought but always looking to learn more.
