Question

All of the following are correct about the indirect ELISA, except:

a. Detecting Antibodies in Serum
b. Common Screening Test for Helicobacter Antibodies
c. Color Development Indicates Absence of Antibody
d. Common Screening Test for Hepatitis A Antibodies
e. Known Antigen Adsorbed to Well Surface

Answer 1

The indirect ELISA is a common screening test that detects antibodies in serum by attaching a known antigen to the well of a microtiter plate. The color development indicates the presence of the antibody.

Step-by-step explanation:

The correct option about the indirect ELISA is: c. Color Development Indicates Absence of Antibody. Indirect ELISA is a common screening test for detecting antibodies in serum.
