When performing phenotyping, which antigens are typically analyzed?

• A. Only glycoproteins
• B. Only glycolipids
• C. Both glycoproteins and glycolipids
• D. Neither glycoproteins nor glycolipids

Answer: (C)

Phenotyping involves the identification and evaluation of various antigens present on the surface of cells, particularly red blood cells. When performing phenotyping, both glycoproteins and glycolipids are analyzed because these molecules play significant roles in blood group antigen expression. Glycoproteins are proteins that have carbohydrate groups attached to the polypeptide chain, which can include various blood group antigens such as ABO and Rh antigens. Glycolipids, on the other hand, consist of a carbohydrate and a lipid and are crucial for the expression of other blood group systems, such as the Lewis and Kell antigens. Thus, the correct understanding of phenotyping encompasses the analysis of both types of molecules to provide a comprehensive profiling of blood group antigens, aiding in transfusion medicine and understanding of immune responses. This comprehensive analysis ensures accurate blood typing and compatibility testing, which is critical for safe blood transfusions.
