This derived from grouo B donor
Anti A
Coloring agent of anti A
Trypan blue
Prevent bacterial contam of anti A
0.1% sodium azide
This is derived from group A donor
Anti B
Coloring agent anti B
Acriflavin
Preservative of anti B
0.1% sodium azide
Derived from group O donor
Anti AB
The patient is added to known grp A and Grp B rbc. The presence of anti A and anti B in the pt serum will give a specific pattern of agglutinates
Serum group
To perform the cell grouping, the patient red cell are added to the specific anti sera
Cell grouping
Differ in amount of ag present on the rbc cell membrane,
Abo subgroup
The resukt of less effective enzymes
Subgroup
Subgroup of what ABO are more common than what
A is common than B
Anti A lectin
Dolichos biflorus
This cause mixed field agglutination when plycolonal anti A or anti A1B is used
a3 red cells
This appears small small agglutination with a backgouo of unagglutinated rbc
Mixed field agglutination
