Answer #1

Immunodiagnostics is a diagnostic methodology that uses an antigen-antibody reaction as their primary mean of detection.

A false negative immunodiagnostic test is a test result that indicates a person doesnot have a human protozoan and helminthic infections.This test varies with each infection that cannot be parasitologically diagonised .Most important are malaria,lymphatic etc.

A false positive immunodiagnostic test is a test result that indicates a person has a human protozoan and helminthic infections.

It tests the presence of drugs or alcohol in the body.

We get a negative/positive because of the human protozoan and helminthic infections a person has or not.
