If you have a wearable spectrometer (i.e. measure the wavelengths that are reflected), and a variable light source (i.e. control the frequencies sent into the body), you can isolate repeating patterns, even for molecules like glucose: https://youtu.be/xMa1BQ8z9C0?t=541
I'm still not sure how they can tell the parts per million, etc. Probably through multiple samples over time, or multiple veins.
