Anti-A or anti-B isoagglutinins (alloantibodies) are present only in the blood sera of individuals not possessing that specificity. Due to time for analysis, complexity, and expense of testing for possible reactions among all known antigens, the simpler ABO blood typing system remained the primary method to identify blood.
