Protocol - Body Temperature - Tympanic Thermometers
Protocol Name from Source:This section will be completed when reviewed by an Expert Review Panel.
This protocol provides a description for obtaining body temperature by tympanic (i.e. ear) thermometers.
The following is a summary description for obtaining body temperature by tympanic (i.e. ear) measurement.
Tympanic Body Temperature:
There are many different types of ear thermometers that are appropriate for this protocol. Investigators should follow the manufacturer’s recommendations for calibration and measurement.
To decrease the likelihood of obtaining a falsely low reading, visually check the thermometer for dirt or damage before and after each use.
If using alcohol wipes or wet cloths to clean the probe tip, exercise caution as these items can have a cooling effect.
Place the thermometer probe into the ear canal according to the manufacturer guidelines.
Read the thermometer and record the temperature.
Normal Body Temperature:
96.1 to 99.3
35.6 to 37.40
Personnel and Training Required
Health care professionals trained in the operation of the selected thermometer.
|Average time of greater than 15 minutes in an unaffected individual||No|
|Specialized requirements for biospecimen collection||No|
Mode of Administration
Infant, Toddler, Child, Adolescent, Adult, Senior, All Ages, Pregnancy
The Sickle Cell Disease Cardiovascular, Pulmonary, and Renal Working Group recommends body temperature be obtained by either oral or tympanic (i.e. ear) measurements, and that once selected, the same body site be used over the course of a study. To aid comparability and accuracy, the Working Group also recommends the investigator record the make and manufacturer of the thermometer, and follow their guidelines regarding thermometer use, calibration, storage, and maintenance.

DefinitionA measurement of the heat in an individual’s body, which is reported in either degrees Fahrenheit or Celsius.
Body temperature is associated with the presence or absence of various illnesses and infections and having an abnormal temperature can be an indication for additional medical testing.
The Sickle Cell Disease Cardiovascular, Pulmonary, and Renal Working Group selected an overall description of obtaining body temperature as the protocol because there are multiple body sites which are routinely used in clinical and research practices to obtain temperature. The selected description is comprehensive and provides details on how to use various thermometers, factors which affect accuracy, and the importance of user training.
