Immune Issue: Immunoglobulin g is present in a person's blood to fight infections. There is a range of normal depending on age. If the level is low, that means that either the person is not making enough or the person is losing the igg (in diarrhea). Typically, igg is checked when a person has recurrent, severe or unusual infections. Sometimes the other antibodies will be low (iga, igm) as well.

See an immunologist: Immunoglobulin g (igg) is the main type of antibody found in the blood and is used by your body to help fight off infections. Some people may have a slightly low igg but be perfectly healthy. In others, it may indicate a problem with the immune system that can put one at risk for getting infections. An immunologist can perform additional tests to determine the cause of the low igg.
