Which components are tested in serology?

• A. Antibodies and enzymes
• B. Antigens and antibodies
• C. DNA and RNA
• D. Proteins and carbohydrates

Answer: (B)

The correct answer is the assessment of antigens and antibodies. In serology, the focus is on the immune response in the bloodstream, particularly the presence of antibodies, which are proteins produced by the immune system in response to antigens—substances that the body recognizes as foreign, such as pathogens or toxins. Testing for antibodies can help determine if an individual has been exposed to a specific antigen, which is crucial in diagnosing infections, autoimmune diseases, and other conditions. Similarly, testing for antigens can confirm the presence of a pathogen. This dual testing helps provide a comprehensive understanding of an individual’s immune status and can guide treatment decisions or vaccination strategies. Other options mentioned do not accurately represent the focus of serological testing. For example, while antibodies and enzymes are important in multiple biological processes, serology specifically targets the interaction between antigens and antibodies. Similarly, while DNA and RNA testing falls under molecular biology and genetics rather than serology, proteins and carbohydrates are broader categories that go beyond the direct assessment conducted in serological tests.
