Tests and diagnosis

By Mayo Clinic Staff

The diagnosis of hypothermia is usually apparent based on a person's physical signs and the conditions in which the person with hypothermia became ill or was found. Blood tests also can help confirm hypothermia and its severity.

A diagnosis may not be readily apparent, however, if the symptoms are mild, as when an older person who is indoors has symptoms of confusion, lack of coordination and speech problems. In such cases, an exam may include a temperature reading with a rectal thermometer that reads low temperatures.
