Most of the immunoglobulins are gammaglobulins, so there is not much difference between immunoglobulins and gammaglobulins. Globulins in the human body are divided into α1, α2, β and γ globulins, and γ globulins are also known as gammaglobulins. Since most of the immunoglobulins are gammaglobulins, gammaglobulins are sometimes called “immunoglobulins”, so there is not much difference between immunoglobulins and gammaglobulins. Human immunoglobulins are roughly divided into five categories: lgA, lgG, lgM, lgD and lgE, which have different immune effects. Immunoglobulins in the plasma of healthy people can be made into medicines for the prevention of infectious hepatitis and measles, or used in combination with antibiotics to treat serious infections caused by viruses, bacteria and other pathogens. For matters related to immune globulin and gammaglobulin, patients are advised to go to the rheumatology and immunology department or other related departments in regular hospitals for detailed consultation.
