Which type of antibody is associated with blood group antigens?

Step 1: Understand what antibodies are. Antibodies are proteins made by the immune system to help fight off infections.
Step 2: Learn about blood groups. Blood groups are determined by specific antigens present on the surface of red blood cells.
Step 3: Identify the types of antibodies. There are different types of antibodies, including IgM, IgG, IgA, IgE, and IgD.
Step 4: Focus on IgM antibodies. IgM is a type of antibody that is primarily associated with blood group antigens.
Step 5: Understand agglutination. Agglutination is the clumping of cells, which can happen if someone receives mismatched blood during a transfusion.
Step 6: Conclude that IgM antibodies can cause agglutination when they react with incompatible blood group antigens.
