I wonder if it's possible to design a personal device that can track most of the 100+ biomarkers named in the front page of this website. I guess that do do so it must analyze more than the blood (through LEDs reflections), for example saliva or feces.
After all my watch tracks already 6/7 of them, why not 100?
Long time ago I used a fetal Doppler to detect heart failure in adults. It was not based on LLMs (2016) but on a HMM to learn the hidden states: The heart beats.
It was tested with the Physionet database. It performed quite well, but I didn't invent the algorithm; it came from a Physionet competition.
