Learn how to get an accurate temperature reading at home, using common types of thermometers.
Always use a digital thermometer to check your temperature. Because of the potential for mercury exposure or ingestion, glass mercury thermometers have been phased out and are no longer recommended.
No matter which type of thermometer you use, take these precautions:
You'll need an oral thermometer, used in the mouth.
A digital ear thermometer uses an infrared ray to measure the temperature inside the ear canal.
Temporal artery thermometers use an infrared scanner to measure the temperature of the temporal artery in your forehead.
A digital thermometer can be used in your armpit, if necessary. But armpit temperatures are typically less accurate than oral temperatures.
