Amid the undeterred surge of Covid-19 infectious wave where fever is one of the common symptoms, understanding the difference in accuracy between Temporal Artery Thermometers (TAT) and No-Touch Thermometers (infrared guns) is of utmost importance.

The accuracy of No-Touch Thermometers is in question because recently the first study of its kind to compare the accuracy of No-Touch Thermometers to Temporal Artery Thermometers has been published in the American Journal of Infection Control.

During the observational study when No-Touch Thermometers and Temporal Artery Thermometers were used to collect the body temperature recordings, the body temperatures read below 99.5 degrees Fahrenheit, the thermometers showed similar results, but as temperatures rose above that, No-Touch Thermometers’ accuracy decreased.

The study done on non-infectious patients has also shown promising results in measuring actual body temperature ‘No-touch’ devices are found to be ineffective, while the accuracy of the measurements of Temporal Artery Thermometers (TAT) seems to be promising.

Temporal Artery Thermometers use an infrared scanner to measure the temperature of the temporal artery in the forehead by slightly and gently scanning the forehead. They read the infrared heat waves released by the temporal artery, which is close to the surface of the skin. These show accurate readings in a matter of seconds with accuracy and efficiency.
