  "term": "Predictive value",
  "field": "Chemistry",
  "definition": "A statistical measure that indicates the probability that a test result correctly reflects the true presence or absence of a condition. Positive predictive value (PPV) is the probability that a positive test result is truly positive, while negative predictive value (NPV) is the probability that a negative test result is truly negative. These values depend on the sensitivity and specificity of the test, as well as the prevalence of the condition in the population.",
