Question

Specificity of a Screening Test is:

• A. Ability of the test to identify correctly those who do not have the disease
• B. Ability of the test to identify correctly those who have the disease
• C. The probability that a patient with a positive test has, in fact, the disease in question
• D. The probability that a patient with a negative test does not have the disease in question

Hint:

High specificity means fewer false positives, making it useful in confirming the absence of a disease.

Answer 1

The Correct Option is A

Step 1: Understand the concept of specificity.
Specificity refers to the ability of a test to correctly identify those without the disease, i.e., the proportion of true negatives.
- Sensitivity, on the other hand, measures the ability to correctly identify those with the disease.
