physioex 9.0 exercise 12 serological testing

Activity 3: Indirect Enzyme-Linked Immunosorbent Assay (ELISA).
Why a patient might test indeterminate?
    
Activity 1: Using Direct Fluorescent Antibody Technique to Test for Chlamydia.
How would the results be affected if a negative control gave a positive result?
    
Activity 3: Indirect Enzyme-Linked Immunosorbent Assay (ELISA).
How the direct and indirect ELISA are different?

Activity 1: Using Direct Fluorescent Antibody Technique to Test for Chlamydia.
Explain where the epitope (antigenic determinant) is located
    
Activity 1: Using Direct Fluorescent Antibody Technique to Test for Chlamydia.
Describe the importance of the washing steps in the direct antibody fluorescence test.

Activity 2: Comparing Samples with Ouchterlony Double Diffusion.
Why does the precipitin line form?
    
Activity 4: Western Blotting Technique.
Why the HIV Western blot is a more specific test than the indirect ELISA for HIV?
    
Activity 1: Using Direct Fluorescent Antibody Technique to Test for Chlamydia.
Describe how a positive result is detected in this serological test.

Activity 4: Western Blotting Technique.
Explain the procedure for a patient with an indeterminate HIV Western blot result.
    
Activity 2: Comparing Samples with Ouchterlony Double Diffusion.
Did you think human serum albumin and bovine serum albumin would have epitopes in common?
