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.
