Kinsa takes accuracy very seriously. Typically in “Normal Mode” our Kinsa Smart Stick thermometer takes FDA-cleared accurate oral readings in 10 seconds or less using a predictive algorithm. “Long Reading Mode” (also referred to as Direct Mode) is an alternate way of taking a reading, by measuring body temperature over a longer period of time.
In this mode, it takes several minutes for the reading to complete, and this may not be practical for infants or fussy toddlers!
