Lab MCQs Mock Test Chapter 103 – Immunology & Clinical Biochemistry
Test your knowledge with Lab MCQs Mock Test – Chapter 103. This chapter contains 50 multiple-choice questions, covering MCQs 5101–5150, designed for Medical Laboratory Technicians, Medical Laboratory Scientists, Medical Laboratory Technologists, students, and candidates preparing for laboratory examinations.
Chapter 103 covers important Clinical Biochemistry and Immunology concepts. The questions begin with selected areas of amino-acid metabolism and protein digestion, including albinism, glycine metabolism, histamine formation, DOPA, pepsin, trypsin, chymotrypsin, and pancreatic digestive enzymes.
The chapter then focuses extensively on immunology, including antigens, haptens, epitopes, immunoglobulin structure, light and heavy chains, variable and constant regions, hypervariable regions, and immunoglobulin classes.
Important antibody concepts covered in this chapter include IgA, IgG, IgM, IgD, and IgE, their distribution and functions, secretory IgA, placental transfer, antibody half-life, antigen recognition, and antibody effector functions.
The questions also cover the complement system, including the classical and alternative pathways, C1 components, complement activation, membrane attack complex formation, and the roles of Factors B and D.
The final section focuses on antibody diversity and cellular immunity, including gene rearrangement, immunoglobulin gene segments, heavy-chain classes, T lymphocytes, helper T cells, antigen recognition through MHC proteins, MHC class I, and cytotoxic T cells.
Read each question carefully, select the best answer, and complete the mock test to assess your Immunology and Clinical Biochemistry knowledge and examination readiness.

Review Your Performance
After completing Lab MCQs Mock Test Chapter 103, review your score and identify the questions and topics that require further study.
Begin by reviewing the introductory Clinical Biochemistry topics, including albinism, glycine metabolism, histamine formation from histidine, DOPA in catecholamine and melanin synthesis, and the functions of pepsin and pancreatic proteolytic enzymes.
Next, focus on the fundamental concepts of antigens and haptens. Review the definition and function of an epitope, the characteristics of haptens, and how haptens differ from complete antigens in their ability to stimulate an immune response.
A major section of this chapter covers immunoglobulin structure and classification. Revise the structure of antibody molecules, including light and heavy chains, variable and constant regions, hypervariable regions, and the basis for classification into IgA, IgG, IgM, IgD, and IgE.
Pay particular attention to the major characteristics of individual immunoglobulins. Review IgA and secretory immunity, IgG abundance and half-life, IgM and primary immune responses, and IgE-mediated allergic reactions.
You should also revise the complement system, including the classical and alternative pathways, the C1 complex, complement activation by proteolysis, the membrane attack complex, and the roles of Factors B and D.
Finally, review antibody diversity and cellular immunity, including immunoglobulin gene rearrangement, variable/joining/constant gene segments, heavy-chain diversity segments, T-lymphocyte functions, helper T cells, antigen recognition through MHC proteins, and MHC class I recognition by cytotoxic T cells.
Regular practice with Immunology and Clinical Biochemistry MCQs can strengthen your understanding of antibody structure, immune responses, complement pathways, cellular immunity, and important biochemical concepts, while improving recall and examination confidence.
