The Immunoglobulin-A (IgA) test, also known as the “mucosal immunity assessment,” gauges the blood’s concentration of IgA antibodies. IgA, an essential immune system component, is mostly present in saliva, tears, and the mucous membranes lining the gastrointestinal and respiratory systems. This antibody guards against infections by microorganisms that enter the body through the digestive and respiratory systems, which is important for the immunological function of mucous membranes.The addition of “health heart diagnostics” (HHD) to the definition of mucosal immunity assessment emphasizes the significance of this assessment beyond the realm of the immune system, especially in relation to cardiovascular health. IgA helps to regulate systemic inflammation and infections, which can have an impact on cardiovascular health even though it has no direct effect on heart function. For
