For panel results, which antibodies could not be ruled out?

When analyzing panel results in immunohematology, the primary focus is on the identification of antibodies that may react with red blood cell antigens. The ability to rule out antibodies depends on the specificity of the results and the antigens present on the panel cells.

In this case, the reason the antibody that could not be ruled out is Anti-C is likely due to the presence of the C antigen on the panel red blood cells and the specificity of the antibody under consideration. Anti-C is a clinically significant antibody associated with the Rh blood group system, and it can lead to hemolytic transfusion reactions if transfusions are not compatible. If panel cells that should display the C antigen were selected for testing and show positive reactions with the serum, this indicates the presence of Anti-C and rules out the possibility of it being excluded.

In contrast, antibodies such as Anti-Jkb, Anti-M, and Anti-Fyb may be less significant in certain transfusion settings or may not have been indicated by the panel results, therefore allowing for their exclusion based on the observed reactions and the known characteristics of those specific antibodies. The contextual information of the blood group antigens and the serological reactions plays a crucial role in determining what can be ruled out, and in this
