Body temperature is usually taken at different sites including pulmonary artery, rectal, oral, and axillary areas. Currently, infrared tympanic temperature measurement method is increasingly used as a convenient, noninvasive and rapid method. However, accuracy and precision of this method has been questioned. The aims of this study were (a) to determine accuracy and comparing tympanic temperature with rectal temperature as a gold standard and (b) to determire Precision (Repeatability) of tympanic temperature with single measurement.   Material & Method: This was a descriptive-comparative study with the sample size of 336 subjects, executively selected from the patients who admitted to Rasool Akram Hospital in Tehran. The patients were 16-85 years old. The tympanic temperatures were measured using the Braun ThermoScan type 6020 and the rectal temperatures were measured using the type M9380226 that both thermometers had 0.1 ºC internal error. The tympanic temperatures were measured twice per side with 1 minute of cooling off in each subject.   Result: Paired t-test showed that there was statistical difference between right and left tympanic temperature with rectal temperature (P M3 ER -
