A lab scientist is attempting to develop a screening tool that will detect leukemia before children show any symptoms of the disease, because it is most curable in its early stages
The scientist wants a test that will detect all children, whether or not it produces some false positives. What does the researcher want in terms of that new screening tool? (Select all that apply.)
a. Maximum specificity
b. A high LR–
c. Maximum sensitivity
d. A high LR+
e. High interrater reliability
ANS: A, D
Sensitivity is the ability of a test or diagnostic tool to detect patients with the disease. This is referred to as a true positive. Specificity is the ability of a test or diagnostic tool to detect patients without the disease. This is referred to as a true negative. A test with high sensitivity is very good at identifying the diseased patient. A high positive Likelihood Ratio makes a positive diagnosis almost certain. A high negative Likelihood Ratio makes a negative diagnosis almost certain.
