Medical testing seeks to use reproducible tests, i.e. where a repeat test would show exactly the same results even when the tester does not know the original results.
For instance … patch testing, skin prick testing and scratch testing are highly reproducible, but are not necessarily accurate, as they only measure the reaction of the skin to a potential allergen. The skin tissues do not necessarily react in the same way as, for example, the lining of the lungs or the stomach. In consequence there are likely to be some false-positive results (i.e. suggesting the person is allergic to something when they are not) or false-negative results (i.e. suggesting the person is not allergic to something when they are).
