Screening tests vs diagnostic tests


Cliff

Recommended Posts

Hi,

I understand the requirement to use FDA approved tests to screen blood products.

What I wanted to know is, are we allowed to use those same screening tests for diagnostic testing? If you could provide links guidance documents (or point me in the right direction) that would be very helpful.

Thank you.

From a quick lecture I had in SBB school, donor screening tests are approved by a different process at the FDA than are diagnostic tests. It has to do with sensitivity vs specificity. So if I remember correctly, if a manufacturer submits to both processes and gets approved twice, then yes we could use it. But as SMW stated, it depends on the manufacturer.
