Everything needed for blood grouping
1/3 anti of blood grouping
2 / A needle free germ

Anti-A in the first drop of blood, keeping the distance as instructed in the picture

Mix well with Anti-D at the base of the needle in the 3rd drop. Make sure that one does not mix with the other while mixing blood & anti.
Now the rules of blood grouping: –
