What is the Wiener nomenclature for the E antigen?

• A. hr ́
• B. hrv ́
• C. rh ̋
• D. Rh0

Answer: (C)

The Wiener nomenclature system describes blood group antigens based on their genetic inheritance and phenotypic expression. The E antigen, which is part of the Rh blood group system, is specifically designated as rh ̋ in this nomenclature. In this system, the lowercase "h" indicates the presence of the Rh factor, while the accent mark (ˋ) distinguishes the specific antigen type, in this case, indicating the E antigen. This notation is integral to understanding the complex interactions and inheritance patterns within the Rh blood group system, especially when considering blood transfusions and compatibility. The other options do not conform to the Wiener nomenclature for the E antigen. For instance, hr ́ and hrv ́ refer to different antigenic entities within the same Rh system, while Rh0 is part of the Fisher-Race system, which uses a different nomenclature altogether and refers to the Rh-positive state rather than a specific antigen like the E antigen.
