Immunoglobulin G (IgG)

Immunoglobulin G (IgG) is a type of antibody found in our blood, playing a crucial role in the immune system. It helps identify and neutralize foreign substances, like bacteria and viruses. IgG makes up about 75-80% of the antibodies in your body and is vital for long-term immunity. When you’re exposed to an infection or vaccine, your body produces IgG to remember and fight off the disease more effectively in the future. Essentially, IgG is key to protecting your body from sickness and ensuring a swift response to pathogens you’ve encountered before.
