WEBJun 30, 2018 · Background. Sensitivity and specificity are characteristics of a test. Positive predictive value (PPV) and negative predictive value (NPV) are best thought of as the clinical relevance of a test. The significant difference is that PPV and NPV use the prevalence of a condition to determine the likelihood of a test diagnosing that specific ...
