About the test

This test measures glial fibrillary acidic protein (GFAP), a protein found primarily in astrocytes, which are supportive cells in the central nervous system. GFAP levels may help assess injury or damage to the brain and nervous system and are sometimes evaluated in the context of neurological conditions, traumatic brain injury, and neuroinflammatory disorders.
