IgG

The IgG test, also referred to as the immunoglobulin G assay, is a blood-based assessment aimed at quantifying IgG antibody concentrations in the bloodstream. These antibodies, crucial elements of the immune system, are generated upon exposure to distinct pathogens (such as viruses, bacteria) or substances like food and medications. This diagnostic tool serves diverse functions: detecting past or recent infections by identifying specific IgG antibodies, pinpointing potential allergic responses by observing heightened IgG levels to particular allergens, and aiding in the monitoring of conditions like autoimmune diseases or responses to specific therapies. By scrutinizing IgG levels, healthcare practitioners glean essential insights into an individual’s immune activity and potential health-related indications.
