Calculation for PPV
The people with a +ve result who actually have the disease
Calculate NPV
The people with a -ve results who do not have the disease
How does PPV changes with prevalence
Predictive values are dependent on underlying prevalence therefore an increase in prevalence will result in an increase in the PPV
How does sensitivity change with prevalence
Remains the same as is a test dependent marker
