IgG stands for Immunoglobulin G. It is a type of antibody found in blood and extracellular fluid, allowing it to control infection of body tissues. IgG is the most common type of antibody in circulation, playing a key role in the body's immune response by identifying and neutralizing pathogens such as viruses and bacteria.

FAQs & Answers

  1. What is the function of IgG? IgG plays a crucial role in the immune response by identifying and neutralizing pathogens like viruses and bacteria.
  2. How is IgG measured? IgG levels can be measured through blood tests, which help assess immune function or diagnose certain conditions.
  3. What are the different types of antibodies? There are five main types of antibodies: IgG, IgA, IgM, IgE, and IgD, each with specific roles in the immune system.
  4. Why is IgG the most common antibody? IgG is the most common antibody in circulation because it is highly versatile and effective in response to infections.
