How accurate is the forehead thermometer?
Forehead thermometers are increasingly in use because they are simple to operate and can take readings without human contact. However, they can be less accurate than other thermometers, such as mouth or ear thermometers, especially if people don't use them properly.
A forehead thermometer provides a quick, sterile way to assess a person's temperature. They use infrared trusted source sensors to measure temperatures. Compared to other thermometers, children's thermometers are easier to use and easier to use for rapid assessment of large groups of people.
This paper compares the accuracy of forehead thermometer with other thermometers. It will also look at how forehead thermometers work, how to use them and the best way to take your temperature.
How accurate are they?
For general use at home, forehead thermometers will give an idea of whether or not an individual has a fever.
However, according to a 2020 study, forehead thermometers are not a reliable source of accuracy compared to other methods of reading temperature, such as mouth, rectum or eardrum (ear) temperature readings.
The results can also be inaccurate if a person wears a headband or headband before taking the drug, or has sweat or dirt on their forehead.
A 2013 study comparing forehead and ear thermometers found that both devices returned lower readings than rectal thermometers.
