Based on what has been presented, the cut-off value of the second test should be different bilchemia two patients suspicious for the same disease but having different results on their first test, hence different post-test probabilities. Errors of Observation and Their Treatment. The higher the NNM of a test, the closer is the test to the gold-standard, hence, hopoer better test. Biochemia Stryer – 1.
