Question: We have two tests to diagnose a serious prognosis disease. Test A has a sensitivity of 95% and a specificity of 60% and test B has a sensitivity of 70% and a specificity of 99%. We have an effective treatment but that produces important adverse effects and also has a very high cost. What test would we choose to make the diagnosis? 
 Options:  <1> Test A because it will detect less false positives. <2> Test A because it has a higher sensitivity. <3> Test B because it will detect more false positives. <4> Test A because it will detect more false negatives. <5> Test B because it has a greater specificity.
