Ques Sensitivity of a diagnostic test is defined as the probability that a diseased individual will have a positive test result (or positivity in diseased). Specificity is defined as the probability that a disease-free individual has a negative test result (or negativity in healthy). A recent study evaluated the diagnostic ability of elevation of cardiac troponin T as a marker for myocardial infarction (MI).

(A) Sensitivity will increase and specificity will decrease

(B) Sensitivity will decrease and specificity will increase

(C) Both sensitivity and specificity will increase

(D) Both sensitivity and specificity will decrease

(B) curve 2

(C) curve 3

(D) curve 4

(A) streptomycin

(B) penicillin

(C) tetracycline
