Based on the provided cell panel, which antibody is most likely present if results show strong reactivity?

In the context of blood bank serology, the presence of an antibody can often be deduced from the reactivity patterns observed in a cell panel. A strong reactivity typically indicates a significant clinical or immunological correspondence between the serum and the cells tested.

Anti-C is an antibody associated with the Rh blood group system, primarily reacting with red blood cells that carry the C antigen. If the cell panel shows strong reactivity specifically correlating to antigens from the Rh system, it suggests that the patient’s serum is highly reactive to the C antigen presented on the test red blood cells. The presence of anti-C would indeed create strong agglutination with cells expressing the C antigen, which aligns with the results observed in the test panel.

When interpreting results, one should also consider the characteristics of other antibodies being tested. For example, anti-E and anti-D are also part of the Rh system but may not show as strong reactivity if they are not the target antigen present in the tested cells. Similarly, anti-K (Kell system) would primarily react with cells that express the K antigen, which could vary in strength depending on the expression of the antigen in the tested panel.

Therefore, the rationale for concluding that anti-C is most likely present
