Background:
The aim of this study was to compare temperature readings measured at the forehead and wrist against the tympanic temperature which is generally accepted as the standard.
Method:
This is a cross-sectional study carried out on 325 people from the general population entering a private hospital for consultation or work. Forehead and wrist temperature was taken using the CEFC RoHS K3 model (China) and tympanic temperature using the Braun Thermoscan 7 Thermometer Irt6520 by the same investigator on consenting individuals.
Results:
There was no significant difference between the forehead (mean =36.6, standard deviation, SD=0.30) and tympanic (mean=36.6, SD=0.41), Z= -1.609, p=0.108. However, there was significant difference between the wrist (mean=36.4, SD= 0.28) and tympanic (mean=36.6, SD=0.41) temperature values, Z= -8.749, p<0.001, the former being lower. Temperature measured at forehead (mean=36.6, SD=0.30) was also significantly higher than the wrist (mean=36.4, SD=0.28), Z= -9.381, p<0.001. The wrist temperature values were lower than forehead and tympanic.
Conclusion:
Forehead temperature values are better representatives of the core temperature (tympanic) and be the preferred site of measurement compared to the wrist.

Glass-bulb Thermometer:
Glass-bulb thermometers are hollow glass tubes with a bulb tip containing liquid such as ethanol or mercury. Historically, glass bulb mercury thermometers were the standard device to measure body temperature. Today, mercury thermometers are prohibited in many countries due to the hazardous effects of mercury and the risk of exposure if the glass bulb breaks. In general,...
