The thermometer I have is the kind you point at someone's head. Clearly it's a scam. At times, I'll pull the trigger and the number that I get seems almost right. At other times, the readout is absurd.
The published evidence on fever guns is damning. One study from the FDA compared their readings, as produced under ideal conditions, with those from oral thermometers; it found that they were often grossly out of whack.
The very best-performing models were able to detect a threshold fever-100.4 degrees Fahrenheit-about two-thirds of the time; the very worst could never make the proper diagnosis.
