<h3>IgG: What Does It Mean?</h3>
  • Known as immunoglobulin G, It is an antibody of some sort.
  • Your immune system produces antibodies, which are proteins, to combat pathogens.
  • Your cerebrospinal fluid's levels of IgG are measured using a CSF IgG index.
  • Normally, your cerebrospinal fluid contains very little IgG.

<h3>What is the role played by IgG in the body?</h3>
  • IgG is typically the most prevalent antibody in blood.
  • It guards against infections.
  • Therefore, infections are more likely to affect those with IgG deficiencies.
  • Your body produces unique proteins known as immunoglobulins or antibodies when it senses an attack.

<h3>When IgG is positive, what happens?</h3>
  • The presence of IgG indicates that the infection occurred several weeks to months ago.
  • Additionally, it implies that you might no longer be contagious.
  • IgG suggests that you might have some viral immunity, though you might not.
