Indirect EIA is Used to Detect

Question

Indirect EIA is used to detect
A) antigens.
B) antibodies.
C) viruses.
D) serum.

Accepted Answer

Indirect EIA is commonly used to detect antibodies. It relies on the binding of an antibody to a particular antigen, and the detection of that antibody through a secondary reaction with an enzyme-linked detection system. This can be useful for identifying disease-specific antibodies in patient serum or for monitoring the immune response to a particular pathogen or vaccine.
