An antibody, also known as an immunoglobulin, is a large, Y-shaped protein that is used by the immune system to neutralize pathogens. The antibody recognizes a unique molecule of the pathogen, called an antigen, and neutralizes it. [adapted from wikipedia]. This class represents various types of antibodies, the presence or absence of which are the object of a laboratory test. The antibody is typically represented by a SNOMED code.

Red blood cell antigens present other than ABO and Rho(D). [FileMan 63.07->63.13] These are the patient's identified antibodies. [FileMan 63.075->63.075] Red blood cell antigens absent other than ABO & Rho(D). [FileMan 63.08->63.016] These are eluate antibodies. [FileMan 63,1->63.01,3->63.012] Antigens present on RBC's of patient are entered here. [FileMan 63,1->63.01,6.1->63.011] Antigens identified as absent on red blood cells are entered here. [FileMan 63,1->63.01,6.2->63.0112] These are the serum antibodies. [FileMan 63,1->63.01,7->63.46]

A record of blood that has been (or will be) transfused to a patient, and the laboratory tests that have been performed on that blood product.

This is blood bank data on this patient. [FileMan 63,1->63.01]

Blood products and reagents for blood banks and transfusion services. [FileMan 66]

These are blood component requests. [FileMan 63,.084->63.084]

This is data concerning the patient's transfusion. [FileMan 63,.085->63.017]

Transfusion reactions that cannot be assigned to a specific unit are entered here. [FileMan 63,.086->63.0171]
