Is a skin thermometer accurate?
The sensitivity and specificity for the non-contact thermometer is 97%. The negative predictive value is 99%, which is especially important to rule out fever and avoid unnecessary laboratory work-up.
How do you measure surface temperature of skin?
The most common method of skin temperature measurement is the use of a mercury-in-glass thermometer, which is used both in the home and in hospital settings. The measurement of temperature from the skin surface of the forehead can be measured by using liquid crystal thermometers.
