To Remember Immunoglobulins- “GAMED”

IgG

  • the most abundant type of antibody, is found in all body fluids and protects against bacterial and viral infections.

IgA

  • is found in high concentrations in the mucous membranes, particularly those lining the respiratory passages and gastrointestinal tract, as well as in saliva and tears.

IgM

  • is found mainly in the blood and lymph fluid, is the first antibody to be made by the body to fight a new infection.

IgE

  • is associated mainly with allergic reactions (when the immune system overreacts to environmental antigens such as pollen or pet dander). It is found in the lungs, skin, and mucous membranes.

IgD

  • which exists in small amounts in the blood, is the least understood antibody.
