The best rectal thermometer is taking an individual’s temperature by inserting a thermometer into the rectum via the anus. This is generally considered the foremost accurate means of temperature-taking, but some may consider it invasive or humiliating.
A rectal thermometer is a medical device designed to measure body temperature by insertion into the rectum. It consists of a slender, flexible, and typically bulb-shaped tip made of a heat-conductive material such as glass or metal. The thermometer also features a handle or base that allows for easy gripping and manipulation.
To use a rectal thermometer, the tip is gently inserted into the rectum through the anus, a short distance inward. The thermometer is left in place for a brief period, usually around one minute, to allow the tip to accurately measure the internal body temperature. Once the measurement is complete, the rectal thermometer is carefully removed and the temperature reading is observed from a display on the handle or base of the device.
Rectal thermometers are considered one of the most accurate methods of measuring core body temperature, as the rectal area closely reflects the body’s internal temperature. They are commonly used for infants, young children, and individuals who cannot cooperate in oral or tympanic (ear) temperature measurements.
Do not take a rectal temperature if your child has had surgery on his rectum, has any quiet rectal disorder, or if he bleeds easily.
