Maybe someone can help me answer this question.....I am a B- CMV negative blood donor and just found out what my blood type is because it was my first time.....I have a concern.....In the next 1-2 months I will be going into a fairly invasive surgery that may require a blood transfusion.....I have plans to have an autologous transfuision(meaning store my blood before the surgery just in case). ..What happens if I can't get enough and I need to have someone elses blood?....Must it be B- as well as CMV negative?.....What if the blood I receive is positive for CMV? Will I be O.K.? or will I have CMV for life?...Is it curable??? Help.....
