Infrared Forehead Thermometer Accuracy

are forehead thermometers accurate
Are forehead thermometers accurate?

Temporal artery thermometers, known as forehead thermometers, use an infrared scanner to measure the temperature of the temporal artery in the forehead.

They can read a person’s temperature very quickly, are easy to use, safe, and easily tolerated by children and babies.

With some thermometers, you don’t even have to touch the skin to read the temperature, which makes them best for testing sleeping children – without waking them up and disturbing them.

They make the best fit for infants older than 3 months and older children, and according to the Mayo clinic, new research suggests that they may also be used for newborns.

 Are they accurate? 

The latest research suggests that forehead infrared thermometers are the most accurate alternative to rectal digital thermometers for taking a child’s temperature.

However:

Remember that the environment around you may influence your skin temperature. The tested child/adult needs to be in the same steady room for 30 minutes if you want an accurate read.

Do you add a degree with a forehead thermometer?

User manuals report an accuracy of about 0.4 Fahrenheit degrees, which is not ideal, but all the accuracy in the world won’t help if you can’t use it on a temperamental child.

What is Considered a Fever When You Use a Forehead Thermometer?

Checking for fever can be done in different parts of your body, including the armpit, mouth, ears, rectum, and forehead.

  • An ear temp. is 0.5°F (0.3°C) to 1°F (0.6°C) higher than an oral temperature.
  • An armpit (axillary) temperature is usually 0.5°F (0.3°C) to 1°F (0.6°C) lower than an oral temperature.
  • A forehead (temporal) scanner is usually 0.5°F (0.3°C) to 1°F (0.6°C) lower than an oral temperature.

So, what is considered a fever on the forehead?

According to the Seattle children’s hospital, a forehead temperature of 100.4° F (38.0° C) or higher is considered a fever.

Forehead Infrared Thermometer FAQ

What is a normal temperature on the forehead?
The average normal oral temperature is 98.6°F (37°C), while the forehead (temporal) scanner is usually 0.5°F (0.3°C) to 1°F (0.6°C) lower than an oral temperature.
How do you use a forehead thermometer?
If you have a no-touch forehead thermometer, you simply position the device in the center area between the eyebrows, at a 2.5 cm distance. The thermometer will indicate when the reading is done. With a contact forehead thermometer, you’ll need to slowly slide the thermometer across the forehead toward the top of the ear, until the device indicates the reading is done.
What's better - ear or forehead thermometer?
Each of these infrared thermometers has its pros and cons. The ear thermometer can give you more accurate readings with older children who do not mind feeling the probe in their ears. For younger children, the forehead thermometer is ideal as it is gentle and non-intrusive.
