Patients with persistent MOG antibodies may benefit from addition of immunosuppressant agents, which may decrease the number of attacks. It was thought to be associated with steroid-dependent course, and azathioprine and intravenous human immunoglobulin treatment were added. The presence of myelin oligodendrocyte glycoprotein (MOG) antibody may be. Clinical judgement is required when selecting patients for MOG-IgG testing and when interpreting a positive. Aid in diagnosis of CNS demyelinating disease or autoimmune encephalitis. The positivity of this antibody remained. MOG autoantibody We test for serum MOG-IgG antibody using a cell-based assay in patients with characteristic clinical, MRI, and laboratory features of MOGAD and in those with a CNS demyelinating syndrome that is atypical for MS. We were able to search MOG antibody at the ninth attack. During follow-up, she experienced repeated episodes after steroid therapy termination. ADEM was diagnosed and treated with steroid. Periventricular white matter lesions were seen on cranial magnetic resonance imaging studies. A 6-year-old girl was consulted with encephalopathy, gait disturbance, and oculomotor nerve palsy. Here we report a unique case with persistent MOG antibodies presented with multiphasic ADEM-like attacks. However, persistent MOG antibodies are considered as a predicting factor for multiple sclerosis, optic neuritis relapses, and incomplete recovery of ADEM. Aquaporin-4 receptor (AQP4) and myelin oligodendrocyte glycoprotein (MOG) antibody testing is used for diagnosis and evaluation of neuromyelitis optica. group of scientists, anti-MOG antibodies are detected in 21. Different techniques are used to determine the level of MOG- abs in serum, which every laboratory has to specify in their reports. the optic nerves and/or the spinal cord and detection of aquapor- in-4 (AQP-4)-antibodies. MOG antibodies have been shown to be positive in high titers during the first episode of ADEM with rapidly decreasing to undetectable limits after recovery. MOG antibody testing: If the diagnosis MOG-spectrum disease is suspected in a child the investigation of choice is a live cell-based assay ideally performed a specialized laboratory. Methodology Cell-based Immunofluorescence Assay Assay Category This test was developed and its analytical performance characteristics have been determined by Quest Diagnostics.

It may give prognostic information regarding monophasic or recurrent course of the disease. Test Details Includes If the MOG Antibody screen is positive, then a semi-quantitative titer will be performed at an additional charge (CPT code (s): 86362). Myelin oligodendrocyte glycoprotein (MOG) is a candidate target antigen in demyelinating central nervous system diseases, including acute disseminated encephalomyelitis (ADEM), neuromyelitis optica, and multiple sclerosis.
