Immunity testing involves evaluating the immune system's response to pathogens, vaccines, or other immunological challenges, providing insight into an individual's immune status and potential vulnerabilities. It is essential for diagnosing immune disorders, assessing vaccine efficacy, and guiding personalized medical interventions.
Adaptive immunity is a highly specialized and systemic response that develops as a result of exposure to specific antigens, providing long-lasting protection and immunological memory. It involves the activation of lymphocytes, including T cells and B cells, which recognize and remember pathogens, allowing for a more efficient and rapid response upon subsequent exposures.
Innate immunity is the body's first line of defense against pathogens, providing an immediate but non-specific response to invaders. It involves physical barriers, immune cells, and various proteins that recognize and respond to common features of pathogens without prior exposure.
An antibody titer is a laboratory test that measures the presence and amount of antibodies in the blood, indicating the strength of the body's immune response to an antigen. It is crucial for determining immunity levels, diagnosing infections, and guiding vaccination strategies.
Cell-mediated immunity is an essential arm of the adaptive immune system where T cells, rather than antibodies, play the central role in defending against intracellular pathogens, such as viruses and some bacteria. It involves the activation of various T cell subsets that recognize and destroy infected or altered cells through direct contact or by releasing cytokines to modulate the immune response.
An immunoassay is a biochemical test that measures the presence or concentration of a macromolecule in a solution through the use of an antibody or antigen. It is widely used in clinical laboratories for diagnostics, in research for detecting specific proteins or hormones, and in various industries for quality control purposes.

Serology is the scientific study of serum and other bodily fluids, primarily focusing on the detection of antibodies and antigens to diagnose infections and immune responses. It plays a crucial role in diagnosing diseases, monitoring immune status, and conducting epidemiological investigations.
The immune response is the body's defense mechanism against pathogens, involving a complex interplay between innate and adaptive immunity. It includes the recognition of foreign antigens, activation of immune cells, and the elimination of pathogens, while also maintaining tolerance to self-antigens to prevent autoimmunity.
Immunodeficiency refers to a state where the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. It can be congenital, as seen in primary immunodeficiency disorders, or acquired due to factors like infections, malnutrition, or immunosuppressive drugs.
Electromagnetic Compatibility (EMC) ensures that electronic devices operate as intended in their electromagnetic environment without causing or suffering from interference. It is crucial for the reliability and safety of electronic systems, particularly in complex environments where numerous devices operate simultaneously.
Electromagnetic Compatibility (EMC) ensures that electronic devices operate effectively in their electromagnetic environment without causing or experiencing interference. It encompasses compliance with regulatory standards and involves designing, testing, and certifying devices to minimize electromagnetic emissions and enhance immunity.
