BLOOD GROUP

Photo essay from laboratory.
Determination of blood group ABO on plate.
Research of erythrocyte antigens (ABO grouping). Here, mix of the blood of a patient with serums.

A drop of blood of the patient is placed with serums containing antibodies directed again antigens A (blue), B (yellow), A et B (colorless). An agglutination of red corpuscles then indicates the blood group of the patient.
This research erythrocyte antigens (ABO grouping) must necessarily be validated by the research of antibodies in the serum, and be made twice independently.
