Red Blood Cells have specific antigenic markers on their surface. There are two types of protein A and B. If you are type A blood your RBCs have protein A, if you are type B you have B proteins, if you are AB you have both and if you are O you have neither. These proteins are detected by the bodies immune system, which detect the protein specific to you and as a result do not attack that cell.
If you were Group A and were to receive Group B blood, your immune system would attack all the B blood - making it pointless and often dangerous to give it. Blood type O - often called the universal donor - has no antigenic marking proteins and therefore will not be broken down by the recipients immune system.
What else can I help you with?
Is O positive or O negative the universal donor?
O negative is the universal donor.
What blood type is also known as the universal donor?
Blood type O negative is known as the universal donor because it can be transfused to patients of any blood type in an emergency when blood typing is unavailable.
Why O negative blood can be gien to a person in acute emergency when blood of same blood group is not available?
because O negative are universal donor.
What is the unversal donor blood type?
Type O negative.
What blood known as the universal donor?
O negative
Is O positive blood universal blood?
No. O negative is the universal donor.
Which blood type is the universal blood type?
Type O negative blood is a universal donor blood type. In normal circumstances, anyone can receive type O negative blood in a transfusion. When it comes to plasma donation, type AB positive is a universal donor.
Who is universal donor in blood grouping?
O negative blood type is the universal donor, but this only applies in terms of ABO grouping and rh classification. There are exceptions, but O- is often used in an emergency situation until the ability to type and crossmatch is provided. Plasma, however, has the opposite consequences. In terms of plasma, AB is the universal donor. The impact is that whole blood must be matched. If you are giving blood components in an emergency situation, it should only be RBC's or plasma.
is A positive blood a universal donor type?
O negative is the universal donor because when O+ve blood group is transfused to -ve blood group recipient, antibodies are produced which causes hemolysis of Rh +ve labelled blood cells. When O-ve blood is transfused to Rh +ve recipient, no antibodies are produced as donor blood has no Rh factor present on blood cells, so no transfusion reaction occurs. Thus, O -ve is universal donor.
Is o negative the universal donor?
yes it may be because it may be donated to other blood types.
Is O plus Universal Donor?
No it is not..The blood group is O negative.
What do you call the universal blood donor?
O Rh D negative
