Blood Types
There are four different blood types in the world :
AB-O-B-A
With different negative or positive rhecus (Rh).
To find them we undertook three tests, one for the A type, one for the B type and the last for the Rh.
We placed a pallet three drops of blood and we searched which type of blood it was.
For example if the blood agglutinated for test A, this blood belonged to A type.
We did the same for the B type and the rhecus.
And if the blood didn't agglutinate in the A and B place, this was O type.
