ABSTRACT
The basic concepts on the application of the BINARY TABLE and how to estimate the SENSIBILITY, SPECIFICITY an the LIKELI-HOOD RATIO of a diagnotic test are reviewd. The latter is particularly useful in the decision making regarding the correct selection of additional diagnostic tests. A practical nomogram can be applied with the previous knowledge of the likelihood ratio and quickly decide if a given result confirms or not an initial diagnostic impression. The methods use for the evaluation of diagnostic tests are powerful instruments not only for the diagnostic decision making but are furthermore the basis for the critical appraisial of clinical studies where the eficacy of a diagnostic test is promoted
