Prevalence (pre‐test probability) = 525÷5,650 = 9.3%;
Sensitivity = 430÷525 = 81.9%; Specificity = 4,900÷5,125 = 95.6%; PPV = 430÷655 =
65.6%; NPV = 4,900÷4995 = 98.1%.
The prevalence is relatively high (but for diabetes realistic) compared to most 'common'
diseases, and together with a pretty accurate test this gives a high PPV.
