We also got blood samples from the 5 suspects at the crime scene, who had hex nuts in their car. Procedure To determine the blood type found at the scene we used a process called agglutination using Anti-A serum and Anti-b serum to test for a positive or negative agglutination. We also took both the hex-nuts from the crime scene and the hex-nuts we found at the crime scene and did a test called water displacement to figure out if each sample is made of the same material, to get a more accurate result we tested each size hex-nut 3 times using the exact same methods each time. Results After the agglutination test you can see what the blood type was found at the crime scene and what the suspects blood type is.
