How accurate is Duo?

+/- 1˚C for each temperature component and +/- 15% for each time component.
The run rate of the blue dye across the time markers is calibrated to a temperature of 2˚C above the stated threshold temperature. For example, the time markers for the 10˚C threshold indicator in Duo are calibrated to a temperature of 12˚C/54°F. If the vaccine being monitored breaches its threshold temperature and is held at a constant temperature (i.e. isotherm) of 12˚C, the blue mixture will reach the 3 day print mark within 3 days (+/- 15% in time).
