Question

If a doctor wanted to run a blood test to determine whether or not a person was immune to the measles virus, would they need to look for measles antigens or measles antibodies? EXPLAIN YOUR ANSWER.

Answer 1

Answer:

The answer is antibodies.

Explanation:

Antigens are the molecules in the body that have the ability of causing an immune response to a disease whereas antibodies are protein molecules that are produced by the cells in the immune system for each specific disease. So if a doctor wanted to find out whether the person is immune to a disease or not by running a blood test, the focus should be on the presence of antibodies.
