Some of the highlights of this episode include:

  • IVDs are a Specialized Medical Device: Learn how IVDs, which include reagents, instruments, or systems for diagnosis, differ from other medical devices and what specific regulatory pathways they follow.
  • Risk Levels in IVDs: Understand the significance of classifying IVDs into class one, two, or three based on the risk of false or inaccurate results, and how this impacts regulatory strategy.
  • Pitfalls in Performance Characteristic Evaluation: Discover the complexities involved in evaluating the performance of multiband diagnostics and why traditional measures like sensitivity and specificity may not suffice.
  • Likelihood Ratios Over Sensitivity and Specificity: Grasp why likelihood ratios are a more appropriate statistical measure for multiband diagnostics and how they relate to pretest and posttest probabilities.
  • Clinical Relevance is Key: Recognize the importance of ensuring that the markers detected by IVDs are clinically meaningful and relevant to the condition being diagnosed.
  • FDA's Expectations for IVDs: Gain insights into the specific data and performance characteristics the FDA looks for in IVDs and the necessity of clinical data in regulatory submissions.


Memorable quote:

"With IVDs, you're looking at it from the perspective of what's the risk of a false result or an inaccurate result. So you're looking at who's interpreting the results and the type of condition." - Carmen Brown
