Red cell affinity column technology (ReACT) was a method for detecting any clinically important antibodies in patient serum.Whereas gel agglutination is based on size exclusion of agglutinated red cells in an inert matrix, red cell affinity column technology was based on affinity adherence of red cells in an immunologically active matrix.
Blood compatibility testing is routinely performed before a blood transfusion.The full compatibility testing process involves ABO and RhD (Rh factor) typing; screening for antibodies against other blood group systems; and crossmatching, which involves testing the recipient's blood plasma against the donor's red blood cells as a final check for incompatibility.
The Colton antigen system (Co) is present on the membranes of red blood cells and in the tubules of the kidney [1] and helps determine a person's blood type. The Co antigen is found on a protein called aquaporin-1 which is responsible for water homeostasis and urine concentration. [2]
An antibody elution removes bound antibody from the surface of a red blood cell to aid in the antibody identification process. An antibody elution is a clinical laboratory diagnostic procedure which removes sensitized antibodies from red blood cells, in order to determine the blood group system antigen the antibody targets.

Anti-K is the next most common immune red cell antibody after those in the ABO and Rh system. Anti-K typically presents as IgG class alloantibody. Individuals lacking a specific Kell antigen may develop antibodies against Kell antigens when transfused with blood containing that antigen. This is particularly true for the "K" antigen which shows ...
The direct Coombs test is used to detect antibodies or complement proteins attached to the surface of red blood cells. To perform the test, a blood sample is taken and the red blood cells are washed (removing the patient's plasma and unbound antibodies from the red blood cells) and then incubated with anti-human globulin ("Coombs reagent").
This antibody is associated with WBC. It is associated more with tissue antibodies than red blood cells. It has not been associated with autoimmune hemolytic anemia of the fetus. However, it does cause difficulty in the blood bank because it makes it more difficult to cross match blood for transfusions.
The Royal College of Obstetricians and Gynaecologists (RCOG) is a professional association based in London, United Kingdom. Its members, including people with and without medical degrees, work in the field of obstetrics and gynaecology , [ 1 ] that is, pregnancy , childbirth , and female sexual and reproductive health .
