Measuring body chemistry at home

Cue is a health tracker that measures inflammation, vitamin D levels, fertility, influenza, and testosterone.  Its creators claim to bring tests that were previously only available in the lab into the home.  The system sends customized alerts with suggestions on how to improve one’s health.

A droplet of saliva, blood, or a nasal swab is added to a cartridge. and paced inside Cue, which sends the analysis to a smartphone or tablet via bluetooth.
