What does active Go mean?

Autoimmune diseases. Autoimmune disease refers to the disease that the body reacts to its own antigen, resulting in damage to its own tissue, usually manifested as active go, so active go is an autoimmune disease. Immunity is a physiological function of the human body, and the human body relies on this function to identify "self" and "non-self" components, thus destroying and rejecting antigen substances entering the human body, or damaged cells and tumor cells produced by the human body itself, thus maintaining human health.
