Part Description

LP411550-9   Glial fibrillary acidic protein.alpha subunit Ab.IgG
Glial fibrillary acidic protein (GFAP) antibody is a biomarker for immune inflammation. GFAP IgG autoantibody binds to GFAPα, and is found in serum and cerebrospinal fluid (CSF) of indiviuals with GFAP astrocytopathy. GFAP antibodies are detectable by immunofluorescence (IF), cell-based assay (CBA) and western blot. GFAP astrocytopathy often overlaps with other autoimmune diseases, making diagnosis challenging due to the coexisting neural autoantibodies. [PMID:30568655] Source: Regenstrief LOINC
