Summary Introduction
Introduction:
Serology is a method which is used to analyze the blood for the presence of a specific antibody and antigens. There is wide-range of serological tests available to recognize the antigens or antibodies in the blood. Using tagged or labelled antibody to identify an antigen is an altered form of serological testing method, for example, fluorescent antibody tests.

Which of the following is the correct pairing of an immunologic test and the subject to be identified? a. indirect ELISA test/an unknown microbial antigen b. direct fluorescence antibody test/an unknown antibody c. Western blot/an unknown microbial antigen or antibody d. agglutination test/an unknown soluble microbial toxin
An MLS has completed an antibody panel using PEG. She cannot exclude anti-Fya, or anti-E. Anti-Kpª and anti-Ja cannot be excluded either but they are low incidence antigens and the MLS is not concerned with those at this time. What would be the next logical step to aid in antibody identification?
a. Run the panel again using ficin treated cells
b. Run the panel again using 22% albumin for enhancement
c. Pay special attention to the strength of the agglutination reactions
d. Run the panel again but increase the 37 degree incubation time to one hour
Which of the following components can be used in
an ELISA?
