What is Dengue serology IgG iGM?

Dengue serology IgG IgM test is a medical diagnostic test used to determine the presence of antibodies against the dengue virus in the person’s blood sample. This test helps to detect a recent or past infection of the dengue virus. The test measures the levels of two types of antibodies: immunoglobulin G (IgG) and immunoglobulin M (IgM) antibodies.

Immunoglobulin G (IgG) antibodies: These antibodies are produced in response to a dengue virus infection and can persist in the blood for several months to years, indicating a past infection.

Immunoglobulin M (IgM) antibodies: These antibodies are produced early in the course of a dengue virus infection and typically decline within a few months. The presence of IgM antibodies indicates a recent infection.

A positive result for dengue serology IgG IgM test, either IgG or IgM antibodies depending on the stage of the infection, suggests a current or recent dengue virus infection.

This test is commonly performed when a person has symptoms that are consistent with dengue fever, such as fever, headaches, muscle aches, joint pain, nausea, and vomiting. The test results help physicians diagnose a dengue virus infection and distinguish it from other similar illnesses, such as malaria, typhoid, or chikungunya.
