Biomarker Reference · GFAP IgG
Glial Fibrillary Acidic Protein Antibodies IgG (GFAP IgG) is a clinical biomarker used in neurological-mental-health assessment. Glial fibrillary acidic protein is an intermediate filament found in astrocytes; serum GFAP has been studied as a biomarker of astrocytic injury in trauma, stroke, and neurodegenerative disease. It is measured in 1 laboratory test on BiomarkersLabs.com.
Glial fibrillary acidic protein is an intermediate filament found in astrocytes; serum GFAP has been studied as a biomarker of astrocytic injury in trauma, stroke, and neurodegenerative disease. Antibodies to GFAP, distinct from measurement of the protein itself, are occasionally seen in autoimmune encephalitides and as an exploratory marker in functional panels.
GFAP antibodies may reflect astrocytic damage or autoimmune reactivity but are not yet validated for routine clinical use. They are measured in exploratory contexts or as part of broader autoimmune encephalitis work-ups.
Reference ranges vary by laboratory and assay platform. Interpret in context of the issuing laboratory's stated range.
