Is it accurate to take temperature under armpit?

Taking temperature under the armpit, or axillary temperature, can provide a general estimate of body temperature, but it is typically less accurate than other methods, such as oral or rectal measurements. Factors like sweat, ambient temperature, and improper technique can affect the readings. While it's a convenient option, especially for quick checks in children, it's best to confirm with a more accurate method if precise temperature is needed.
