What Is Axillary Temperature?
Axillary temperature is a body temperature measurement taken under the arm (in the axilla). It is a simple, non-invasive method commonly used for infants, children, older adults, and individuals who cannot safely use oral temperature measurements.
Although convenient, axillary temperatures are generally slightly lower than oral or rectal temperatures and may be less accurate for detecting fever.
Why Axillary Temperature Matters
Monitoring body temperature helps identify fever, infection, hypothermia, and other medical conditions. Regular temperature checks are especially important for people recovering from illness or surgery and those with weakened immune systems.
When Is Axillary Temperature Used?
- Routine health assessments
- Monitoring for fever
- Infants and young children
- Older adults
- Home healthcare visits
- Postoperative recovery
How Is Axillary Temperature Measured?
- Place the thermometer high in the center of the dry underarm.
- Lower the arm firmly against the body.
- Wait until the thermometer signals that the reading is complete.
- Record the temperature and report any unusual readings if instructed.
How Home Care Can Help
Home care professionals monitor body temperature, recognize signs of infection or illness, educate caregivers on proper thermometer use, and report concerning temperature changes to the healthcare provider.
Home Care Tip
For the most accurate reading, ensure the underarm is dry and the thermometer remains fully covered by the arm throughout the measurement.
Frequently Asked Questions About Axillary Temperature
Is an axillary temperature as accurate as an oral temperature?
Axillary temperatures are convenient but are generally slightly lower and less accurate than oral or rectal temperature measurements.
When should an axillary temperature be repeated?
If the reading seems inconsistent with a person’s symptoms or appears unusually high or low, your healthcare provider may recommend confirming it with another method.
Can home care professionals monitor body temperature?
Yes. Home care professionals routinely monitor temperature, recognize signs of illness, and communicate significant changes to the healthcare team.
When to Contact Your Healthcare Provider
Contact your healthcare provider if you develop a persistent fever, unusually low body temperature, chills, confusion, or other signs of infection or illness.
