diagnosis of viral infections sometimes involves analyzing the patients blood for specific ____ that the immune system produces against the virus.
a complement proteins
b glycoproteins
c antigens
d antibodies

Explanation:

Antibodies are proteins produced by the immune system in response to foreign substances like viruses. They are specific to the virus and can be detected in blood for diagnosis. Complement proteins assist in the immune - response but are not the specific molecules produced against the virus for diagnosis. Glycoproteins are a type of protein with sugar chains and are not the key molecules here. Antigens are foreign substances that trigger the immune response, not what the immune system produces against the virus.

Answer:

D. antibodies
