Advanced spectroscopic devices

A mobile device for determining levels of a biomarker of a user, comprising:

• an illumination train configured to emit light comprising a first wavelength;
• a detector train configured to collect emission signals resulting from the light interacting with the user;
• and
• a controller configured to:
• measure emission counts of the emission signals over a period of time;
• cause to be determined at least one of (i) a level of the biomarker of the user and (ii) a change in the levels of the biomarker of the user over the period of time based on the measured emission counts;
• and
• generate a notification indicative of the at least one of (i) a level of the biomarker of the user and (ii) a change in the levels of the biomarker of the user over the period of time.

A mobile device for determining levels of a biomarker of a user, comprising:

• an illumination train configured to emit light comprising a plurality of wavelengths;
• a detector train configured to collect emission signals resulting from the plurality of wavelengths interacting with the user;
• and
• a controller configured to:
• measure emission counts of the emission signals over a period of time;
• with a trained model, cause to be determined at least one of (i) a level of the biomarker of the user and (ii) a change in the levels of the biomarker of the user over the period of time based on the measured emission counts;
• and
• generate a notification indicative of the at least one of (i) a level of the biomarker of the user and (ii) a change in the levels of the biomarker of the user over the period of time.
