What is a normal rectal temperature?
Normal Temperature Range
Rectal. A reading of 98.6° F (37° C) is just the average rectal temp. A normal low can be 96.8° F (36° C) in the morning. It can change to a high of 100.3° F (37.9° C) late in the day.
What is difference between oral and rectal thermometer?

The oral thermometer has a longer thinner tip. The shape of the rectum thermometer is made blunt, short and with a rounded tip to avoid injury.
What is the normal range for a rectal or tympanic temperature?
