Assessment | Serology & Blood Spatter

A protein in the blood that destroys or inactivates a specific antigen is called..

• Erythrocytes

• Antibody

• Antigen

• Enzyme

A process where the red blood cells clump together by the action of an antibody.

• Agglutination
• Enzyme
• Phenotype
• Genotype

Where are antigens located?

• Inside a red blood cell

• Surface of red blood cell

• In the serum of the blood

• In the plasma of the blood

Which blood components are directly important to the forensics aspects of blood identification?

• Hemoglobin and red blood cells

• Serum and red blood cells

• Platelets and white blood cells

• Plasma and red blood cells

This is responsible for transporting oxygen (O₂) throughout the body.

• Hemoglobin in Erythrocyte

• Plasma in the blood

• Platelets in the blood

• Leukocytes in the blood

Where are antibodies located?

• Inside a red blood cell

• Surface of red blood cell

• In the serum of the blood

• In the plasma of the blood

Type A blood contains:

• A antibodies and B antigens.

• both A and B antigens.

• A antigens and B antibodies.

• both A and B antibodies.

To determine whether a bloodstain is of human or animal origin, the serologist will perform:

• Kastle-Meyer Color Test.

• Benzidine Color Test.

• Hemastix Strip Test.

• Precipitin Test.

If blood is found to have both A and B antigens on the cell surface it is typed as:

• A

• B

• O

• AB

An individual who is type O blood has:

• Neither A nor B antibodies

• A antibodies

• B antibodies

• Both A and B antibodies
