Blood is one of the lively chemical element of the human body that carry oxygen to the different parts of the consistence , produces antigen and exemption boosters in the body and facilitates the workings of all the reed organ . In this clause , we look at types of blood groups and matching and sympathise under what conditions stemma transfusion is done . Here , we also talk about the guard that should be take before bloodline transfusion .
Blood Groups
When we peach about blood groups we are discuss the unlike classifications of blood that is done based on the antibodies and the unlike antigenic bodies that are inherit from the parent and the families . These element are present on the surface layers of red stock cadre ( RBCs ) or in the human blood . These antigens principally comprise carbohydrates , proteins , glycolipids or glycoproteins , which again vary in dissimilar blood groups . rakehell types are always inherited from parent and brand a contribution from both the parents .
Researches done in the domain has marked the existence of nearly 36 unlike lineage group system with a presence of nearly 346 antigens . Out of the 36 blood group systems , the Rh factor and the ABO lineage groups are the most important . These compound scheme denote the blood chemical group type of a person such as A , B , O , and AB . The Rh factor refer whether the D protein is present , or absent . These are the aspects that happen to be so very important for blood blood transfusion and have to be hold in obligatorily before blood transfusion of blood .
Blood Groups and Matching

So when a soul with a blood group A is given a rip blood transfusion from a blood chemical group B person then the pay B blood group cells can clomp intravenously that can be deadly for the somebody have the rip transfusion . The same can be said about any other shape of mismatch line of descent transfusion . At the time of blood transfusion , the RhD agent that denotes the positive ( + ) and the negative ( - ) must be borne in mind . A individual who is give birth a positive ( + ) lineage mathematical group can receive lineage from both the RhD sections of the coordinated ABO factor . However , a individual with a negative ( - ) blood radical has to get a blood transfusion from a negative blood radical . masses with a blood radical type O can donate their stemma to people with blood groups A , B complex , and AB . This is because hoi polloi with a blood group O do not have antibodies for both A and B groups of blood . rakehell groups and matching the chemical group before parentage transfusion is called pedigree group compatibility testing . The matching is necessary to avoid incompatibility between the blood groups of the recipient and the donor . Hence they should be check for their blood group and their compatibility or matching must be substantiate .
Under What Conditions Is Blood Transfusion Done?
