A fever is regarded as a rectal, ear or temporal artery temperature of 100.4ºF (38ºC) or even higher. If you are using an oral or oral pacifier thermometer, many doctors would say that a fever can be over 100.4ºF (38ºC), but some can think about a fever in a young individual, to be an oral temperature of 100ºF or 37.8ºC. Speak to your doctor about what temperature range they would think about a fever and concerning the suggested treatment. Together with the axillary (armpit) temperature, a fever is present if the reading is 99.4ºF or higher or over 37.2ºC, but others consider 99.0ºF for a fever, depending upon your doctor’s recommendation. Remember, for all these systemic auto inflammatory diseases, it’s not merely a fever. Your child may “only” be at 99.5 degrees F, but feel miserable. Therefore symptoms and the way you or your kid feels need to be regarded as well when making treatment decision.

Temporal thermometer readings average about the same as rectal and ear thermometer readings in some studies, but lower in others. These thermometers seem to have the most inconsistencies in how they compare to other methods. Differences may be due to which brand was used in the study and if the patients were febrile or healthy. Also, incorrect use of these thermometers will make them inaccurate. Be sure to read the instructions as these have a specific method of use. For example, the forehead thermometer requires that you scan the forehead and artery behind the ear while holding the button down the entire time. Lifting off the button too soon will give you a lower reading. The following video demonstrates how to use the forehead thermometer.

In the past, people used glass mercury thermometers, but that is now not recommended, and they ought to be disposed of in a proper collection facility. There are a number of safe and accurate strategies to take temperature available which is preferred for patients. Generally, Oral and axillary temperature roughly differences 0.5 F to 1.0 F (.3 C to .6 C) degrees below rectal, ear, and rectal on readings. Add .5 to 1.0 when taking orally or under the arm to ascertain the comparable rectal temperature. Eating and drinking can affect the accuracy when taking an oral temperature. Wait 15 to 30 minutes after eating and drinking before taking an oral temperature. Axillary, where you measure the temperature under the armpit, can be reliable for getting an accurate body temperature, also can register up to a degree lower than rectal or other methods of taking the internal temperature. Nonetheless, it’s still considered acceptable if performed correctly and is used in many hospitals. This method can be performed more accurately if the thermometer is properly placed in the deepest pit component of the axilla (armpit), and stored at that place, with the arm folded down and above the thermometer, until the thermometer is done testing the temperature. This method is the most used by many of patients, since a fever can be carried out with any digital or regular (non-mercury) thermometer, and also the least expensive thermometer on the market. It may also be the most convenient for traveling, since they are small and simple to replace. A rectal temperature is usually considered to be the most accurate, and the norm for tracking the core body temperature, but it’s usually not suggested for use in patients, because of the risk of rectal perforation and tears with this method. Have another thermometer to use for oral than for rectal.
