Question

The University of Minnesota and the Mayo Clinic are close to developing a test for COVID-19 antibodies in our blood (They may have already accomplished this by the time you do this extra credit).

Individuals may have COVID-19 antibodies in their blood because these antibodies are produced by A. T-cells, B. b-cells, C. Neutrophils in order to A. Prepare for possible infection, B. Signal to the adaptive immune system that a foreign antigen is present, or C. Combat a foreign antigen.

In order to check for these antibodies, they would use a(n) A. ELIZA or B. PCR in order to identify individuals who A. Have not yet been infected, B. Are healthy enough to combat the virus or C. Have been infected and have recovered from the virus and A. Are free to move about society and donate plasma for treatment of others or B. Need to stay at home.

Answer 1

1. B) . b- cells.

Antibodies are produced by specialized white blood cells called B lymphocytes

2. C) combat a foreign antigen.

Antigens are proteins that are found on the surface of the pathogen, the antibodies destroy the antigen (pathogen) which is then engulfed and digested by macrophages.

3.A) Eliza

An enzyme-linked immunosorbent assay, also called ELISA or EIA, is a test that detects and measures antibodies in your blood. PCR tests are used to directly detect the presence of an antigen, rather than the presence of the body’s immune response, or antibodies

4. C.) Have been infected and have recovered from the virus

Normaly people who are infected by virus, they produce antibodies against these virus, which can be used by other people to combat these virus.

5.  A ). Are free to move about society and donate plasma for treatment of others
