Nope.It is preferred but not as big as a concern
Do platelet transfusions require the same compatibility requirements of blood transfusions?My son is a 7 week old male. When he was 4 days old he needed a platelet transfusion. His blood type is O- and the donor was B+. From what I understand, an O- blood type can only receive O- donor blood. But what about platelet transfusions? His chart labeled the transfusion " Pheresed Platelets." He was in the NICU during this time and I don't really remember why he needed a platelet transfusion. He had two blood transfusions because his hemoglobin was 3.7 at birth but I don't see any tests results for platelets in his chart until the day after his platelet transfusion so I'm not sure if they were low before. I can bring this question up at his next doctor's appointment but I just wanted to get a sense first if it's normal/ok to give platelet transfusions from a B+ donor to an O- recipient.If we call platelet transfusion day Day 1 then his platelet levels were as follows:-Day 2: 58-Day 4: 40 and later 43-Day 5: 46-Day 6: 49-Day 9: 127They eventually got up into the 200s and most recently was in the 500s. We are working with hematology right now but I just thought I'd share the results in case it's pertinent.
