An apparatus of use in identifying neuropathy in the feet of a subject is disclosed, the apparatus comprising means for measuring the temperature of the foot of a subject means for comparing a first measured temperature obtained from one of the subject with a second measured temperature obtained from the other foot of the subject and means for providing an indication to a user when the difference between the first and second measured temperatures exceeds a predetermined amount. A method method determining the relative temperature of the feet of a subject is also disclosed, the method comprising measuring the temperature of a first foot of the subject measuring the temperature of a second foot of the subject comparing the first measured temperature with the second measured temperature to determine the difference therebetween and providing the user with an indication when the difference between the first and second measured temperatures exceeds a preset value.
