What David said is correct. If you know the time it spent and at what temp then you may accept that it be transfused to that patient and deduct the time from the 4 hours. This goes back to the question of why we accept only 30 mins out and back at the acceptable temp and yet allow up to 4 hours of transfusion time. Same concept. Thanks Dave, I had archived that one in my brain.
Positive Cxms and neg AbSc reasons: 1. low incidence antigen on donor cells. 2. Donors are (all) DAT positive 3. Homozygous expression on donor cells and hetero on screening cells for a given Ag 4. Delay between Cxm pos and neg, the interfereing "stuff" settled. 5. AbSc done in tube while gel Cxms more sensitive 6. Patient is weak D with a weak anti-D 7. Patient has excess proteins causing pos result in gel, these are washed away in the tube method. 8. Patient has antibodies against stuff in gel (cxm). >>> more?? I shall await your reply to the questions about what you did asked by the posters.
Once thawed and not released immediately, the FFP is stored at 2-6 C then they transfuse them at 4C slowly as the RBCs. However, in TTP with FFP replacement this is a problem. what do you do, use a warmer? any other options? Thank you.
You do know that an open (spiked) bag can be kept for a maximum of 24 hours at the right storage temp. So having said that, beyond 24 hours if you culture the bag you may end up with a positive culture, while the bag actually did not transmit a bug to the nenate during transfusion.
and by definition how much is in a pack? (it varies based on.. the request?) so no one divides the aphresis collect to suffice 2 patients (if 12 units) oh oh and so may i assume that you write the absolute # of plts on the bag and not # of units like 6 or 10 ( each unit represntiong .55 x 1o^11)? sorry fo spelling etc.... really did get not to the coffeee yet, i am so happy i am getting replies to this quetsion (question). THANK you all.. have a good Sunday and pls continue clarifying these facts to me.
do they use something like tje Atreus? I am working with a European govt now to write a standard National law, i understood that nearly all of Europe give a pool of 5 because the 5 actual have more plts than an apheresis of 6 because of the way they are collected from the Atreus (buffy coat).
