Three tests need to be undertaken  

1)The major test where 3 drops of plasma from the '''recipient''' and one drop of red blood cells from the '''donor''' are added together left for 1-3 minutes and then examined microscopically.  If this reaction shows there is agglutination the transfusion should not be performed.

2)Minor test where 3 drops of '''donor''' plasma is added to 1 drop of '''recipient''' red blood cells. If agglutination occurs then transfusion can occur but with constant monitoring of the patient.

3)A control reaction must also be carried out with 3 drops of '''donor''' plasma and 1 drop of '''donor''' red blood cells. If agglutination occurs then there is an error and the test must be repeated.
