No, it does not. Kinsa reports the temperature accurately, so a reading under the arm will be lower than an oral reading. However, our fever guidance feature takes this into account. It knows to mark a 99.4 F (37.4 C) underarm temperature as a low fever, because it is equivalent to a 100.4 F (38 C) oral temperature.
NOTE: The Mayo Clinic shows this for fever equivalencies:
“The following thermometer readings generally indicate a fever:
- Rectal, ear or temporal artery temperature of 100.4 (38 C) or higher
- Oral temperature of 100 F (37.8 C) or higher
- Armpit temperature of 99 F (37.2 C) or higher” *
