On the Changes of Irregular Agglutinin Titers after Blood Transfusion

Abstract

The irregular changes of MN agglutinin titer after blood transfusion was studied. Blood was obtained from the cubital vein of the lung tuberculosis patient who was transfused the blood over 2000ml.
1) The increase of M agglutinin titer at 5°C was observed in one of 30 cases tested, but this titer did not show any changes at 37°C.
2) One case showed increase of the cold agglutinin titer.
3) The increase of complete antibody titer resulted in 10 of 21 cases tested and decrease in only one case. The increase of anti-A agglutinin titer in O typed patient was observed.
