People with Group O blood wait longer for a heart transplant than those with other blood groups. However, the overall median adult waiting times to heart transplant are 1 :. The longer waiting times arise because people with Group O blood can donate to every other group but they can only receive organs from people who are also Group O. In contrast, patients with AB group blood can receive organs from every other group. The organ usually ceases to function.

Apart from ABO and Rhesus system, many other types of antigens have been noticed on the red cell membranes. Blood grouping and cross-matching is one of the few important tests that the anaesthesiologist orders during perioperative period.

Hence, a proper understanding of the blood group system, their clinical significance, typing and cross-matching tests, and current perspective are of paramount importance to prevent transfusion-related complications. Nonetheless, the knowledge on blood group system is necessary to approach blood group-linked diseases which are still at the stage of research. This review addresses all these aspects of the blood groups system.

Over a period of time, our understanding on blood groups has evolved to encompass not only transfusion-related problems but also specific disease association with RBC surface antigens. Karl Landsteiner has been credited for the discovery of ABO blood group system in He was awarded Noble Prize in for this discovery. His obituary lists an immense contribution of more than publications. Later, Jan Jansky described classification of human blood groups of four types.

At present, 33 blood group systems representing over antigens are listed by the International Society of Blood Transfusion. The antigens can be integral proteins where polymorphisms lie in the variation of amino acid sequence e.

Some of the important groups are mentioned here [ Table 1 ]. H-antigen is the precursor to the ABO blood group antigens. As H-antigen acts as precursor, its absence means the absence of antigen A and B. However, the individuals produce isoantibodies to H-antigen as well as to antigens A and B. Rhesus-system is the second most important blood group system after ABO. RBC surface of an individual may or may not have a Rh factor or immunogenic D-antigen.

Accordingly, the status is indicated as either Rh-positive D-antigen present or Rh-negative D-antigen absent. These immune antibodies are immunoglobulin G IgG in nature and hence, can cross the placenta.

Prophylaxis is given against Rh immunization using anti-D Ig for pregnant Rh-negative mothers who have given birth to Rh-positive child. The blood group is under control of an autosomal locus on chromosome 4 and also under control of a pair of co-dominant alleles LM and LN. Anti-M and anti-N antibodies are usually IgM types and rarely, associated with transfusion reactions.

Lutheran system comprised of four pairs of allelic antigens representing single amino acid substitution in the Lutheran glycoprotein at chromosome Antibodies against this blood group are rare and generally not considered clinically significant.

These erythrocyte antigens are the third most potent immunogenic antigen after ABO and Rh system, and are defined by an immune antibody, anti-K. It was first noticed in the serum of Mrs. She reacted to the erythrocytes of her newborn infant resulting in hemolytic reactions. Since then 25 Kell antigens have been discovered. Duffy-antigen was first isolated in a patient called Duffy who had haemophilia.

It is also known as Fy glycoprotein and is present in the surface of RBCs. It is a nonspecific receptor for several chemokines and acts as a receptor for human malarial parasite, Plamodium vivax. Kidd antigen known as Jk antigen is a glycoprotein, present on the membrane of RBCs and acts as a urea transporter in RBCs and renal endothelial cells. Kidd antibodies are rare but can cause severe transfusion reactions. These antigens are defined by reactions to an antibody designated as anti-Jk a , discovered in the serum of Mrs.

Kidd who delivered a baby with HDFN. Jk a was the first antigen to be discovered by Kidd blood group system, subsequently, two other antigens Jk b and Jk3 were found. Agarwal et al. The remaining 23 are characterized by the protein sequence of the RBC membrane protein,[ 6 , 7 ] five major proteins DI, Rh, RhAG, MNS, GE, and CO among them are expressed at higher levels and function as membrane transporters, whereas the functional importance of rest of 17 antigens is unknown. The ABO blood groups have a profound influence on haemostasis.

Increased association of myocardial infarction, ischemic stroke, and venous thromboembolism is seen with blood groups A and AB[ 13 ] possibly through functional ABO glycol transferases modulation of thrombosis.

A higher risk of cerebral venous thrombosis has been reported in non-O groups. A positive correlation has been shown between blood group A with chronic hepatitis-B infection and pancreatic cancer;[ 16 ] and blood group B with ovarian cancer. After the decision to transfuse blood is taken the next step should be to order a requisition during which the following steps need to be remembered.

The most fatal of all transfusion-related reaction is ABO incompatibility causing complement-mediated intravascular hemolysis. Hence, correct blood grouping and typing, and cross-checking with the blood requisition form is of utmost importance. Cross-matching involves mixing of donor RBCs with the recipient serum to detect fatal reactions.

The third phase consists of the addition of antiglobulin sera to the incubated second phase reactants to detect incomplete antibodies of Rh, Kidd, Kell and Duffy. Among the three phases, the first two phases are more important as they detect those involved in fatal HTR. The total time taken for all the three phases is in between 45 and 60 min. Here, commercially prepared RBCs with all the antigens, which direct production of antibodies causing hemolytic reactions, are mixed with the recipient's serum to detect the presence of those very antibodies.

It is also carried out with the donor's serum. There are controversies regarding the best method for procurement of blood during elective and emergency situations: a It can be done by routinely asking for grouping and cross-matching in elective surgical patients.

Many scientific articles disputed the relevance of preoperative arrangement of blood in surgeries where blood loss is not anticipated to be significant. Antibody screening increases this safety margin up to In absence of cross-matching, there is a possibility of missing the antigens on donor cells, but in clinical practice, they are of less importance.

Three main antigen-modulation strategies have been proposed to prevent immune recognition of incompatible RBCs and to avoid haemolytic reactions due to alloimmunization.

The first approach relies on enzymatic conversion of specific blood group antigens, that is, manipulation of the ABO system. In contrast with the B antigen, enzymatic conversion of A antigen was difficult due to existence of two Type-A blood group structures A2 and A1. The third approach involves in vitro production of RBCs with a predefined antigenic profile from genetically manipulated stem cells. Currently, our knowledge on blood groups goes beyond the usual tests of agglutination and transfusion to the better understanding of RBC antigens in light of their association with multiple diseases and the scope of use of this knowledge to modulate the disease processes.

In this context, the role of adequate understanding of screening, typing, and cross-matching apart from awareness on evolving trends, for every clinician, may not be overemphasized.

Blood Type Compatibility

There are actually three tests that are done to evaluate donors. They are blood type, crossmatch, and HLA testing. Blood Typing There are 4 different blood types. The most common blood type in the population is type O. The next most common is blood type A, then B, and the rarest is blood type AB. The blood type of the donor must be compatible with the recipient. The rules for blood type in transplantation are the same as they are for blood transfusion.

Patients with certain bloods group wait much longer for heart transplants

Because those with type O blood do not have any antigens, they can donate blood to individuals of any group A, B, AB, or O and thus are known as universal donors. Thus, type A can receive blood only from individuals of groups A or O, and can donate blood to those with type A or AB. Thus, type B can receive blood only from individuals of groups B or O, and can donate blood to those with type B or AB. Thus, an individual with type AB blood can receive blood from any group. Because those with type AB blood can receive blood from any group, but cannot donate blood to any group other than AB, they are known as universal recipients.

Incompatible Blood Types and Paired Exchange Programs

As we've learned in one of our previous charts , many people do not know their blood type or that of their close family. Even less know how compatible their type is with others if it were to come to an emergency and they'd need a blood donation. In fact, not all humans have the "same" blood and the distribution of these types varies according to the genetic characteristics of populations. Globally, the most common is group O whereas the rarest is group AB. According to the site rhesusnegative.

Matching blood groups

Before you receive a transfusion, testing is done between the donated blood and a sample of your own blood to check for compatibility. Antibodies are attack molecules our immune system makes to protect us against foreign things such as bacteria and viruses. Antibodies can also form in response to different blood groups. Everyone is born with some antibodies and develops others over their lifetime. ABO is the major blood group system and is genetically determined. The Rh blood group system has around 50 different red blood cell antigens. The percentage of Rh negative people varies in different countries. Some people who are RhD negative will have an immune response to RhD and make antibodies.

The theory goes like this: Your blood type can make you more or less susceptible to various health outcomes, like risk for certain diseases, fertility, reaction to stress , and the composition of bacteria in your gut. Therefore you should eat a diet that helps minimize those specific risks that come with your blood type.

Blood Safety and Matching

Blood typing is the first blood test that will determine if your blood is compatible with the potential donor's blood. If the donor's blood type works with your blood type, the donor will take the next blood test tissue typing. Kidney donors must have a compatible blood type with the recipient. If blood types are not compatible, the donor will not be able to donate directly to you. However, the donor may consider donating through a paired exchange program.

AB Blood Type Diet Chart

Each letter refers to a kind of antigen, or protein, on the surface of red blood cells. For example, the surface of red blood cells in Type A blood has antigens known as A-antigens. Each blood type is also grouped by its Rhesus factor, or Rh factor. Rhesus refers to another type of antigen, or protein, on the surface of red blood cells. The name Rhesus comes from Rhesus monkeys, in which the protein was first discovered.
