Body temperature, like blood pressure, varies from person to person and during the day it may range from 35.5°C to 37.8°C. The temple temperature is converted by the NoTouch Thermometer to the commonly used oral temperature. For some people it may show some difference from their normal oral temperature, thus it is recommended to learn and recognize the forehead temperature while healthy. For continuous accurate results, measure at the same area of the temple each time a temperature is taken.
