The body's immune response: the role of antibodies in laboratory diagnostics<\/h2>\n

Blood test for IgG and IgM<\/strong> \u2014 is a laboratory test that detects the presence of antibodies to certain infections. Such tests are widely used to diagnose viral, bacterial, and parasitic diseases, as well as to assess the stage of the infectious process.<\/p>\n

Antibodies are protein molecules produced by the immune system in response to an invading pathogen. They help the body recognize and neutralize viruses, bacteria, and other pathogens.<\/p>\n

That is why the IgG and IgM analysis is an important laboratory diagnostic tool.<\/p>\n

IgM and IgG: What is the difference between the main types of antibodies?<\/h2>\n

In clinical practice, two types of antibodies are most often tested: IgM<\/strong> and IgG<\/strong>.<\/p>\n

IgM are antibodies that appear first after infection. Their presence usually indicates acute or recent infection<\/strong>.<\/p>\n

IgGs are formed later, but can persist in the body for a long time - sometimes for life. Their presence often means that the body has has already been in contact with the pathogen and has formed immune memory<\/strong>.<\/p>\n

Thanks to the simultaneous determination of IgM and IgG, the doctor can understand at what stage the infectious process is.<\/p>\n
