Esther, Please do not rely on the advice of your pediatrician in this case. It is most assuredly NOT wise for you to donate blood for your baby. Consider this...if your baby does have an "issue" due to your antibodies, you don't want to potentially introduce more of those same antibodies into the baby's system. Yes, washing removes almost all of the plasma from a unit of blood--ALMOST being the key term here. Also, it is not standard practice for any Blood Bank I have ever worked in to wash cells. Now it is left to the reference labs--you are looking a huge time delay there. It is most certainly better to have your baby transfused with donor blood that is negative for the antigens that you have antibodies to.
