The key difference between neutralizing and binding antibodies is that neutralizing antibodies are the antibodies that neutralize the effect of an antigen while binding antibodies are the antibodies that bind with the antigen (without affecting the infectivity), tag, and alert immune cells in our body to recognize them. An antibody is an immunoglobin produced by […]

The key difference between radioimmunoassay and immunoradiometric assay is that in radioimmunoassay, the sample or compound to be measured is combined with a radioactive antigen before the combination, while in the immunoradiometric assay, the sample or compound immediately combines with the radiolabeled antibodies. An immunoassay is a biochemical test that detects the presence or concentration […]

The key difference between autoimmune disease and immunocompromised is that an autoimmune disease occurs when the immune system erroneously attacks the normal healthy cells in the body, while immunocompromised occurs when the immune system fails to respond to an infection or disease adequately. The immune system is a biological network of processes that protects people […]

The key difference between herd and ring immunity is that herd immunity develops when a significant portion of a population is vaccinated while ring immunity develops when all susceptible individuals in a prescribed area around an outbreak of an infectious disease are vaccinated. Vaccination develops immunity in the body. Upon vaccination, people develop immunity against […]

The key difference between O and H antigen is that O antigen is the outermost portion of the bacteria’s surface covering while H antigen is the slender threadlike structure that is part of the flagella. Antigens are molecular recognition sites present in many bacteria, fungi, viruses, dust particles and other cellular and non-cellular particles which […]

The key difference between granular and agranular leukocytes is that granular leukocytes have granules in their cytoplasm, but agranular leukocytes lack granules in the cytoplasm. Leukocytes or white blood cells are one of the main types of blood cells. They are spherical in shape and colourless compared to red blood cells. The number of WBCs […]

The key difference between alloantibody and autoantibody is that the alloantibody is an antibody produced against alloantigens, which are foreign antigens introduced by transfusion or pregnancy. Meanwhile, the autoantibody is an antibody that reacts with self-antigens. Antibodies are produced as a result of an immune response. They may reflect the presence, nature and intensity of […]

The key difference between phagocytosis and opsonization is that phagocytosis is a mechanism executed by certain cells or organisms to ingest or engulf foreign particles while opsonization is the process by which pathogens are removed from the system upon being marked by means of opsonins. Immunologic responses can be innate or adaptive. Pathogens possess pathogen […]

The key difference between cell mediated and antibody mediated immunity is that cell mediated immunity destroys infectious particles via cell lysis by cytokines, without the production of antibodies, while antibody mediated immunity destroy pathogens by producing specific antibodies against antigens. Cell mediated immunity and antibody mediated immunity are two types of primary defence mechanisms taking […]

The key difference between immunosuppression and immunodeficiency is that immunosuppression refers to the reduction of the efficiency of the immune system, while immunodeficiency refers to the inability of the immune system to fight against infectious agents. The immune system detects a wide array of infectious agents entering our body and protects us from diseases. Therefore, […]
