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.
