What is a "normal" axillary temperature compared to oral temperature?

Axillary temperature is generally recognized as a reliable indicator of body temperature, though it is often slightly lower than oral temperatures. Typically, an axillary temperature is approximately 0.5 to 1°F lower than an oral temperature due to the location of measurement and the way the body dissipates heat. This difference arises because the axilla (armpit) is not as centrally located in the body as the mouth, and it can be affected by external factors. This characteristic makes it essential for healthcare professionals to note the method of temperature measurement and understand the expected variations based on that context.

Understanding this relationship is crucial for accurate assessment and monitoring of a patient’s temperature, ensuring that healthcare decisions are based on reliable data.
