The existing literature suggests that infrared thermometer may miss a significant fraction of patients with pyrexia, giving a false sense of safety. The handheld infrared thermometer does not measure the temperature accurately. The personal experience of the individuals using it presently is that the temperature recorded by the infrared thermometer is lower than the actual temperature.
