Is agglutinin is called antibody?
Antibodies that produce such reactions are called agglutinins. Better agglutination takes place with IgM antibody than with IgG antibodies. Excess of an antibody also inhibits agglutination reaction; this inhibition is called prozone phenomenon. Agglutination is more sensitive than precipitation for the detection of antibodies.
What does antibodies in blood mean?
