The difference between antinuclear antibodies and immunoglobulins is that antinuclear antibodies are a type of immunoglobulin, and a positive antibody antibody needs to be considered as a possible autoimmune disease. Immunoglobulin is a component of the immune system, reflecting the level of the body’s immune function.
Antinuclear antibody is a kind of immunoglobulin with antibody activity that is activated by the DNA and RNA of the cell nucleus of the body’s own cells and stimulates the B cells to produce and secrete.
Immunoglobulin refers to the chemical structure of globulin, which can be divided into five categories: IgG, IgA, IgM, IgE and IgD, but not all immunoglobulins have antibody activity.
Under normal circumstances, immunoglobulins should all fluctuate within a normal range, which can reflect the body’s level of immune function. However, under normal circumstances, the body should be negative for antinuclear antibodies, and it is recommended to consult a doctor promptly if positive antinuclear antibodies are found.
