Discussion:
Q: Two pediatricians want to investigate a new laboratory test that identifies streptococcal infections. Dr. J uses the standard culture test, which has a sensitivity of 90% and a specificity of 96%. Dr. M uses the new test, which is 96% sensitive and 96% specific.
Review answer is Dr. J will correctly identify fewer people with streptococcal infection than Dr. Childs. Great answer, but textbook lacks specific rationale for this answer.
