Hi--just to make sure here these were white cell antiboidies and not red cell antibodies and this time all you donated was plasma and not whole blood?
Yes, they only detected white cell antibodies, and I only donated plasma. I have AB+ blood, so I have only donated plasma for years, and they've never mentioned antibodies before.
Hi, Dr. Chip:
FYI, in case this comes up again: I tested positive for HLA antibodies, which the blood bank said are normal for women who were pregnant. They have just started informing people about these and being more careful about using blood that has them. So I probably had them, but they just started letting people know. Thanks for your help!
