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: Grasp the concept of specificity.
Specificity indicates a test's capacity to correctly identify individuals who do not have a particular disease; it represents the proportion of true negatives.
- Conversely, sensitivity indicates a test's capacity to correctly identify individuals who do have the disease.
