What is the lower limit for a normal rectal temperature?

The lower limit for a normal rectal temperature is typically considered to be around 97.0 °F. Rectal temperatures are generally higher than oral temperatures and are used as a more accurate measure of core body temperature. The range of normal rectal temperature usually falls between approximately 97.0 °F and 100.4 °F.

In this context, the chosen answer, which states 98.6 °F, represents the average normal body temperature, but it is not the established lower limit. Many references specify that 97.0 °F is the threshold below which a rectal reading would be considered lower than normal, indicating a potential issue such as hypothermia or under-cooling in a patient. Understanding these ranges is essential for properly assessing a patient’s health and determining if further action or monitoring is needed.
