  • The tests are independent, conditional on disease status (the sensitivity [specificity] of one test is the same, regardless of the result of the other test, as discussed in more detail in the section on series and parallel interpretation of tests);
  • Test sensitivity and specificity are constant across populations;
  • The tests are compared in two or more populations with different prevalence between populations; and
  • There are at least as many populations as there are tests being evaluated.
