Show HN: Best biological age model using standard blood tests

1 points by zsolt224 7 hours ago

There’s a fairly recent research paper introducing a biological age calculation model, that uses only standard blood tests and outperforms PhenoAge. So I reached out to the original researchers and did a 1-hour+ interview with one of the authors. I developed an online calculator based on it and we came up with a name for it: "Bortz Blood Age Calculator"

*About the model:*

- Trained on 306k individuals from the UK Biobank database - Validated on similar dataset - It offers an 11% relative increase in predictive value over the Levine PhenoAge - This model includes better markers (like Cystatin-C, ApoA1...) compared to other similar models. - Interesting thing is that the model selected for higher total cholesterol, ALT and creatinine as better. More about it later.

*Online calculator:*

Based on the model, I created 100% free and private online calculator: https://www.longevity-tools.com/humanitys-bortz-blood-age

*Video*

I also made a video about the calculator, which explains:

- more info about the model and how it was created - gotchas of the calcutor - some speculation about why the model selected for higher total cholesterol, ALT and creatinine
