Robbery of Orient express : Blood types

                     
                  
                       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.



AB+ type
A- type



B- type
O- type
