What is ABO compatible blood?
The blood types must be compatible to avoid an ABO incompatibility reaction. For example: People with type A blood will react against type B or type AB blood. People with type B blood will react against type A or type AB blood. People with type O blood will react against type A, type B, or type AB blood.
Which blood types are compatible for transfusion?
O negative blood can be used in transfusions for any blood type. Type O is routinely in short supply and in high demand by hospitals – both because it is the most common blood type and because type O negative blood is the universal blood type needed for emergency transfusions and for immune deficient infants.
Can O blood type be given to ABO?
As group O red blood cells do not have any A or B antigens, it can safely be given to any other group.
Which blood type causes ABO incompatibility?
ABO incompatibility happens when a mother's blood type is O, and her baby's blood type is A or B. The mother's immune system may react and make antibodies against her baby's red blood cells. The consequences and treatment are similar to Rhesus disease. Check Jaundice in babies.
What is ABO matching?
ABO identical: donor and recipient have the same ABO antigens and antibodies. Major ABO mismatch: donor ABO antigens are incompatible with recipient ABO antibodies. Minor ABO mismatch: donor ABO antibodies are incompatible with recipient's ABO antigens.
Which ABO blood type is considered the universal recipient?
In an emergency situation where a patient's blood type is unknown, type O negative blood is the only blood type that is safe to use. The reason is that it is compatible with all blood types. Type O negative is known as the universal blood type.
Can O receive any blood?
Those with O positive blood can only receive transfusions from O positive or O negative blood types.
Can O Negative receive any blood type?
What blood can O negative people receive? People with O negative blood can only receive red cell donations from O negative donors.
Is O+ and AB+ compatible?
If you have type A blood, you should only receive types A or O blood. If you have type B blood, you should only receive types B or O blood. If you have type AB blood, you can receive types A, B, AB, or O blood. If you have type O blood, you should only receive type O blood.
How do you find ABO incompatibility?
How is ABO incompatibility diagnosed? ABO incompatibility is diagnosed by: (1) cord blood test for incompatibility, (2) a complete blood count (CBC) that shows damaged and hemolyzed blood cells, and (3) elevated bilirubin levels.
Which of the following may show ABO incompatibility?
A person with type A blood receiving a transfusion of type B or AB blood would have an ABO incompatibility reaction. In an ABO incompatibility reaction, your immune system attacks the new blood cells and destroys them. If you have type AB blood, you have both A and B antigens.
Is ABO incompatibility common?
ABO incompatibility is the most common maternal-fetal blood group incompatibility and the most common cause of hemolytic disease of the newborn (HDN). ABO incompatibility is more often seen in newborns who have type A blood because of the higher frequency of type A compared to type B in most populations.
Can O+ receive any blood?
Those with O positive blood can only receive transfusions from O positive or O negative blood types. Type O positive blood is one of the first to run out during a shortage due to its high demand.
Is O+ and B compatible?
If you have type B blood, you should only receive types B or O blood. If you have type AB blood, you can receive types A, B, AB, or O blood. If you have type O blood, you should only receive type O blood.
How do you know if a blood transfusion is compatible?
Humans have 35 major groups or families of these antigens, as well as other minor groups, but consideration of two, the ABO group and the RhD group, is very important to ensure that a transfusion recipient receives compatible blood. The presence of antigens within these groups is what determines a person's blood type.
What is incompatible blood transfusion?
Hemolytic transfusion reaction: Red blood cell incompatibility. Hemolytic transfusion reactions (HTRs) are reactions in which donor RBCs are destroyed by antibodies in the recipient's circulation. They occur when antigen-positive donor RBCs are transfused into a patient who has preformed antibodies to that antigen.
How many different blood groups are there in the ABO?
There are four different ABO blood groups (see Table1), determined by whether or not an individual's red cells carry the A antigen, the B antigen, both A and B antigens or neither. Normal healthy individuals, from early in childhood, make red cell antibodies against A or B antigens that are not expressed on their own cells.
What blood groups are in the human population?
There are many blood groups in the human population including ABO, Rh, Kidd, Kell, Duffy, MNS and Lewis. The most important of these are ABO and RhD. Transfusion with ABO incompatible blood can lead to severe and potentially fatal transfusion reactions. RhD is highly immunogenic and can lead to red cell haemolysis in certain settings.
What happens if you transfuse red cells?
If ABO incompatible red cells are transfused, red cell haemolysis can occur. For example if group A red cells are infused into a recipient who is group O, the recipient's anti-A antibodies bind to the transfused cells. An ABO incompatible transfusion reaction may result in overwhelming haemostatic and complement activation, resulting in shock, renal failure & death (for more information please click here ).
How many different types of antigens are there?
There are more than 40 different kinds of Rh antigens. The most significant Rh antigen is RhD. When RhD is present on the red cell surface, the red cells are called RhD positive. Approximately 80% of the Australian population are RhD positive. The remaining 20% of the population that lack the RhD antigen are called RhD negative.
Can you transfuse a RhD positive red cell?
As a general rule, RhD negative individuals should not be transfused with RhD positive red cells, especially RhD negative girls and women of childbearing age. If transfusion of an RhD positive product to RhD negative recipient is unavoidable a haematologist should be consulted and administration of anti-D immunoglobulin considered.
Can antibodies be produced in a transfusion?
There are many other antigen systems expressed on red cells, white cells and platelets. Transfusion can cause antibodies to develop in the recipient. Some of these antibodies can cause transfusion reactions or damage the foetus.
Are they compatible?
When a transfusion is given, it is preferable for patients to receive blood and plasma of the same ABO and RhD group. However if the required blood type is unavailable, a patient may be given a product of an alternative but compatible group as shown below.
What is the ABO group?
ABO grouping refers to the SURFACE ANTIGENS on our red blood cells (RBCs). For example, type B RBCs have B antigens on their surface while type O RBCs have neither A nor B antigens. Now, one must consider the resulting ANTIBODIES in the plasma. Patients with type A blood have anti-B antibodies in their plasma.
What happens if you have anti-B antibodies?
This makes sense because if they had anti-A antibodies, they would attack their own surface antigens resulting in catastrophic hemolytic anemic. This concept is how we determine compatible blood transfusion options for patients.
Does plasma contain anti-A and anti-B antibodies?
Although their RBCs are devoid of A and B antigens, their plasma contains anti-A AND anti-B antibodies. If this plasma is transfused into a patient with either A or B surface antigens (ABO types A, B, or AB), a transfusion reaction will likely occur.
What blood type is donated to recipients with B and AB?
Blood type B- donate to recipients with B and AB blood types
What blood type is the universal donor?
Blood types O- donate to the recipient with A, B, AB, and O blood types. Blood group O is the universal donor. It is compatible with all other blood types. Only about 4 % of the population donates blood.
What are The Blood Types?
A person’s blood groups are identified by antigens and antibodies in the blood. There are 4 main blood groups or blood types; your blood type is determined by the genes that you inherit from your parents. Every blood group can either be RhD negative or RhD positive, this means that in total there’re 8 main blood groups. They include:
What blood type has antigens?
They include: 1. Blood Group A – This Blood Group has A Antigen on the Red Blood Cells and Anti-B Antibodies in the Plasma. A negative (A-) – Has A marker only. A positive (A+) – Has Rh factor and A marker but doesn’t have B marker. It’s one of the most common blood types. 2.
Which blood group has antigens on the red blood cells?
1. Blood Group A – This Blood Group has A Antigen on the Red Blood Cells and Anti-B Antibodies in the Plasma.
How rare are O and B?
Also, O- and B- are very rare with less than 5% of the world’s population. Usually, individuals with rare blood types bank their lifeblood in advance in cases of surgical procedure to avoid blood unavailability in cases of emergencies.
Which blood group has antibodies?
2. Blood Group B – It has Anti-A Antibodies in the Plasma and B Antigens. B positive (B+) – Has B marker only. B negative (B-) – Has Rh factor and B marker but does not have A marker. 3. Blood Group AB – Has no Antibodies but have Both Antigen A and B. AB negative (AB-) – Has both A and B markers but has no Rh factors.
Which group can donate red blood cells to A's and AB's?
Group A can donate red blood cells to A’s and AB’s. There are more than 600 other known antigens, the presence or absence of which creates "rare blood types.". Certain blood types are unique to specific ethnic or racial groups.
What Is A Rare Blood Type?
There are more than 600 other known antigens, the presence or absence of which creates " rare blood types ." Your blood type is considered rare if you lack antigens that 99% of the people are positive for . If you somehow lack an antigen that 99.99% are positive for, your blood type is extremely rare.
How are blood types determined?
Blood types are determined by the presence or absence of certain antigens – substances that can trigger an immune response if they are foreign to the body . Since some antigens can trigger a patient's immune system to attack the transfused blood, safe blood transfusions depend on careful blood typing and cross-matching.
Why is Type O blood so common?
Type O is routinely in short supply and in high demand by hospitals – both because it is the most common blood type and because type O negative blood is the universal blood type needed for emergency transfusions and for immune deficient infants .
Why is the need for O negative blood the highest?
However, the need for O negative blood is the highest because it is used most often during emergencies. The need for O+ is high because it is the most frequently occurring blood type (37% of the population). The universal red cell donor has Type O negative blood. The universal plasma donor has Type AB blood.
How many blood groups are there?
There are four major blood groups determined by the presence or absence of two antigens – A and B – on the surface of red blood cells. In addition to the A and B antigens, there is a protein called the Rh factor, which can be either present (+) or absent (–), creating the 8 most common blood types ( A+, A- , B+, B- , O+, O- , AB+, AB- ).
How many lives are saved by blood transfusions?
Each year 4.5 million lives are saved by blood transfusions. There are very specific ways in which blood types must be matched for a safe transfusion. The right blood transfusion can mean the difference between life and death. Every 2 seconds someone in the US needs a blood transfusion.

Types
- There are more than 40 different kinds of Rh antigens. The most significant Rh antigen is RhD. When RhD is present on the red cell surface, the red cells are called RhD positive. Approximately 80% of the Australian population are RhD positive. The remaining 20% of the population that lack the RhD antigen are called RhD negative.
Contraindications
- As a general rule, RhD negative individuals should not be transfused with RhD positive red cells, especially RhD negative girls and women of childbearing age. If transfusion of an RhD positive product to RhD negative recipient is unavoidable a haematologist should be consulted and administration of anti-D immunoglobulin considered.
Nomenclature
- Note that Group O RhD negative (O negative) red cells have neither ABO nor RhD antigens on their surface. O RhD negative red cells are issued in emergency situations where life saving transfusion is required prior to completion of a crossmatch. Both RCH and RWH blood banks maintain a reserve of 5 emergency O RhD Negative red cells. (Click here for further information on emergen…
Cause
- Group AB individuals have neither anti-A nor anti-B antibodies in their plasma. Group AB plasma can therefore be given to patients of any ABO blood group and is often referred to as the universal plasma donor. Most ABO incompatible transfusions occur as a result of improper patient identification at the time of collection of the pre-transfusion sam...
Clinical significance
- There are many other antigen systems expressed on red cells, white cells and platelets. Transfusion can cause antibodies to develop in the recipient. Some of these antibodies can cause transfusion reactions or damage the foetus. The purpose of pretransfusion testing (or crossmatching) is to detect potentially harmful antibodies in a patient before transfusion and w…
