Which term means temperature readings taken in the armpit?

The term you're looking for is "axillary temperature." This method involves placing a thermometer in the armpit, where the heat is absorbed from the body. It's handy for quick checks, especially with little ones who might squirm or resist other methods! Despite its convenience, axillary temperature readings can sometimes underestimate the body's true core temperature by about half a degree to a full degree Fahrenheit. So while it’s great for a general idea, if you need precision, especially in a medical context, you might want to consider other methods like oral or rectal readings!
