Question

All are true about Screening tests for a disease except:

• A. Done on apparently healthy people
• B. Not a basis for treatment
• C. Based on one criteria or cut off point
• D. Based on evaluation of number of symptoms, signs and laboratory findings

Answer 1

The Correct Option is D

Step 1: Understanding Screening Tests.
Screening tests aim to find individuals who might have a disease before symptoms appear.
- Screening uses a single criterion or cutoff point (3) and is typically applied to healthy people (1).
- Screening results do not directly determine treatment (2).
- Screening tests differ from diagnostics by not evaluating symptoms, signs, or lab results (4).
