Which of the Following Statements Is Correct Regarding the Relationship

Multiple Choice

Which of the following statements is correct regarding the relationship between immunological quantification by laboratory analysis and biological functionality of the analyte?

A) Immunological quantification and biological functionality are always very closely aligned because of the specificity of the antigen-antibody reaction.
B) Immunological quantification is a more important consideration than biological functionality, because immunological quantification more correctly predicts the activity of the analyte in the body.
C) Immunological quantification may overestimate biological functionality, because the antibody may react with an inactive analyte (such as a metabolite) that contains the antigenic determinant.
D) Immunological quantification will only relate to biological functionality of an analyte if the laboratory analysis is performed on a fresh biological sample within 30 minutes of the time it is received in the laboratory.
