Most patients who receive positive noninvasive prenatal testing (NIPT) results have one question: how likely is it that the result is correct? 

That is why it is essential for health care professionals offering NIPT to understand its performance characteristics, including positive predictive value (PPV). Understanding PPV can help you effectively counsel patients about their positive NIPT results and address their questions. Given that PPVs can vary depending on a woman’s clinical history, age, and on the prevalence of the condition being screened, it is imperative to know how to integrate pertinent information in order to provide the most clinically relevant information to your patient.

This webinar will review some of the statistical terminology that is used in test performance, and also review tools that can be used to calculate PPV with case examples.
