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. Please assist in explaining how the text arrives at this conclusion step by step, so I can have a better understanding on how they arrived at this conclusion.
