jojo808 Posted October 24, 2018 Share Posted October 24, 2018 We've had a very 'old' SOP regarding antigen typing that states we can use an EDTA SPECIMEN for up to 2 days. However when you look at the manufacturer's insert they range from 10 to 14 days refrigerated depending on which antisera you are using. Our preferred specimen for testing is an EDTA sample. Our antisera is 90% Ortho, the other is Biorad. I'm wondering if others are going strictly by the manufacturer's individual instructions or are you kind of using one general expiration time for all antigen type testing??

John C. Staley Posted October 24, 2018 Share Posted October 24, 2018 It's always safest to follow manufacturer's instructions but, generally, it's OK to set your own expiration dates as long as they don't exceed those set by the manufacturer. The easy thing to do if you feel the need to have one sample expiration date for antigen testing would be to check all of the antisera and set your date for the shortest listed. jojo808, TreeMoss, Malcolm Needs and 1 other 4 Link to comment Share on other sites More sharing options...
