About the Accuracy of Ear Thermometers

The eardrum has proven to be a reliable measurement for your body's core temperature. Ear thermometers, also called tympanic or infrared thermometers, have become very popular because they quickly give a temperature. They use infrared radiation to determine temperature. Accuracy depends on using them right.

The human ear is reliable for taking body core temperature.

Brands

Most brands work within acceptable range if used correctly. Choice of brands depends on warranty, ease of use, durability and other features, such as saving past readings.

Age

Ear thermometers are intended for people older than 1 year of age. Infants may have too small of ear canal for proper reading with regular home meters, and pushing too hard can damage their ear canals.

Proper Use

Ear thermometer instructions vary depending on age of user and brand. To get accurate readings, follow the instructions on placement, whether the earlobe or top of ear needs to be pulled, or other directions.

Considerations

Taking your temperature if you have been in very cold or very hot conditions may not be accurate. Wait until your outer ear is near room temperature. If you have wax buildup, it may be necessary to clean your ear.

Medical Use

If the person taking your temperature does not seem to have the device correctly inserted, ask them to retake in the other ear or to let you do it yourself.

Warning

Pushing an ear thermometer too hard into the ear canal can cause damage especially for very young or very old people. Harsh placement is not necessary for accuracy.
