Question

What does a Negative Likelihood Ratio ($LR-$) value close to 0.1 indicate regarding a parallel diagnostic test?
Options
A A negative test result significantly decreases the likelihood that the disease is present.
Correct Answer
B The test has virtually no diagnostic utility and yields random classification.
C A negative test result strongly suggests that the patient is diseased.
D The test displays high cross-reactivity with non-target proteins.
Correct Answer

Option A is the correct answer.

Detailed Explanation

An $LR-$ below 0.1 is considered excellent for ruling out disease, as it substantially lowers post-test probability following a negative result.
