Day 31 Blood Typing Lab
Student Assessment:
Student Lab and Group Work:
Blood typing is done by adding different antigens to blood. If the antigen has an affect on the blood, the blood will clump up.
-There are two types of blood antigen
-Antigen A
-Antigen B
The way we type blood
-There is a blood typing plate that we use that has 3 wells
-You place a drop of blood in each well
-You add a drop of antigen A to one well
-If the antigen A clumps then the blood is A, if it does not clump then the blood is not A
-You add a drop of antigen B to one well
-If the antigen B clumps then the blood is B, if it does not clump then the blood is not B
-If both clump the blood is AB
-If neither clump up then the blood is O
Now lets do a blood typing lab
Here is one of the blood type labs we will do.
