In seroepidemiology when a single sample is taken from exposed and non-exposed subjects, the results of serological tests are usually reduced to a dichotomy: normal (low or no antibodies) or elevated (high or antibodies found).
The choice of the cutoff point between these values has been based on various vaguely defined methods and the results depend, at least partly, on the method chosen.
An alternative method is introduced here which is not based on the absolute value of a serological test but on the rank order of the values of the test.
