Nominal quantities are related to binary results arising from the comparison of a numerical quantity results on an ordinal scale considering a certain decision point or “cutoff.” Sometimes in medical laboratories terminology, nominal tests are referred as qualitative - e.g., agglutination/positive/no-agglutination/negative in a slide, number of crosses of an observed certain reagent - and ordinal tests as semi-quantitative - e.g., positive result given that 4.12 is equal or higher than the “cutoff”=1.00.The validation concepts in this essay only deal with the final binary result that can be applied to any qualitative test. However, the concepts can be applied to any other qualitative test.The comparison of methods can be determined primarily when the comparator is the diagnostic accuracy criteria, or it can be determined secondarily when the comparator is other than the diagnostic accuracy criteria.

In this sampling, the target population is the set of generic healthy individuals.

The area under the receiver operating characteristic (ROC) curve is another diagnostic accuracy measurement, complementary to the sensitivity and specificity [4].
