You can get fast and accurate readings with digital thermometers.  You can use a digital thermometer in three ways:

  • Oral (in the mouth)
  • Rectal (in the bottom)
  • Axillary (under the arm)

Be sure to label your thermometer either “oral” or “rectal” to know the difference.

Taking your temperature orally with a digital thermometer

  1. Wash your hands with soap and water.
  2. Put the tip into a new throw-away plastic cover if one is available. If you do not have a cover, clean the pointed end (probe) with soap and warm water or rubbing alcohol and then rinsed to remove the alcohol.
  3. Do not eat or drink anything for at least five minutes before you take your temperature. You should keep your mouth closed during this time.
  4. Place the thermometer tip under the tongue. Close your lips gently around the thermometer.
  5. Keep the thermometer under your tongue until the digital thermometer beeps. (or hold the thermometer in the same spot for about 40 seconds)
  6. Readings will continue to increase and the F (or C) symbol will flash during measurement.
  7. Remove or eject the throw-away cover if you used one or rinse thermometer in cold water, clean it with alcohol, and rinse again.
