This all sounds exciting, and good luck to all researchers earnestly working on it. If RF blood content diagnostics become possible, blood glucose sensing would be just the start.

But as for this guy and his invention, don’t forget that in clinical setting, Theranos has shown more evidence of their product working. And GlucoWatch, a similar idea two decades ago, was FDA-approved and made it to market though still wasn’t clinically useful due to poor accuracy. Then, I’m not even talking about the charlatan cottage industry around glucose sensing watches, nor am I talking about how CGMs are a (generally) solved problem in diabetes.

Let’s wait for some clinical trials of the applied blood glucose sensing before we pop the champagne? It quite likely won’t happen, welcome as that invention would be.

According to the paper, this worked because the dielectric change from all other blood diagnostics was negligible, allowing glucose to be measured. Gluclose in blood is around 80 mg/dL. It may be possible to measure other blood chemistry metrics that are similar in concentration at other frequencies, but there’s a lot of blood tests, many of which would probably be impossible - like white blood cell count, anything enzymatic, something whose concentration is measured in ug/dL, or something that has no effect on dielectric properties of the blood. I wouldn’t expect to see a whole blood panel via wearable radar anytime soon, but we may get a few more tests from RF sensing.

Good to know I'm not generally then.
