How long must we keep panels? How long must we keep returned signed Rhogam slips? I am starting to go thru all of our patient cards to get head start on this computer system coming. I think I may have Rhogam slips from when Rhogam was invented! LOL...but really not funny...I have a headache again! CAP checklist for record retention says " patient pre-transfusion testing results" 10 years, but then transfusion problems such as transfusion reaction, unexpected antibodies..." says keep indefinitely. So wasnt sure about the panels. I think we need to keep the patient card indefinitely that has the ab id on it, but maybe can discard panel at 10 years? I sure hope so! Thank you for the help!
