Anti-Myelin Oligodendrocyte Glycoprotein Antibodies, which are autoimmune antibodies that are primarily associated with inflammatory demyelinating diseases of the central nervous system, are negative, suggesting that MOG antibodies are not currently present in the body, which is a normal result. Negative anti-myelinating oligodendrocyte glycoprotein antibody is a better diagnostic result, which means that MOG antibodies are not present in the body at present, and it may be the case that the antibodies have gradually turned negative after regular treatment, or that MOG antibodies have never been present. However, if you have previously had optic neuromyelitis optica and test negative for anti-myelin oligodendrocyte glycoprotein antibodies, it does not completely rule out the abnormality because the disease may recur, so it is important to test regularly afterward to find out if the antibodies will turn positive, and if they remain negative, it means that the prognosis for MOG syndrome is good after regular treatment. Anti-myelin oligodendrocyte glycoprotein antibodies are negative and do not require special treatment for the time being, but regular observation and relevant care in conjunction with the doctor’s advice is required.
