Question:
1. The percentage of those with a positive test result who actually have disease is defined as?

2. The percentage of those with a negative test result who do not have the disease is defined as?

I answered positive predictive value(ppv) and negative predictive value(npv) respectively but my professor said it’s wrong and that the answer to these questions refers to individuals

This questions are under the topic sensitivity and specificity of tests in healthcare
