Which statement concerning non-Forssman heterophile antibody is true?

• A. It is not absorbed by guinea pig antigen
• B. It is absorbed by guinea pig antigen
• C. It does not agglutinate horse RBCs
• D. It does not agglutinate sheep RBCs

Answer: (A)

Non-Forssman heterophile antibodies are a specific type of antibody that can react with antigens from different species. In the context of their interaction with guinea pig antigen, saying that non-Forssman heterophile antibodies are not absorbed by it is accurate. This characteristic is significant because it helps differentiate these antibodies from other heterophile antibodies, such as those found in Forssman antibodies, which are absorbed by guinea pig serum. The absorption behavior is essential in the diagnosis and understanding of various serological conditions, particularly those related to heterophile antibodies. The ability of non-Forssman antibodies to remain active despite exposure to guinea pig antigens means that they can still agglutinate cells from other species, which is a distinctive feature in the interpretation of serological tests. This characteristic, therefore, provides valuable information in clinical settings, specifically when distinguishing between different types of heterophile antibodies, leading to a clearer understanding of the immunologic response and the potential diagnostic implications for various diseases.
