Measurement of glial fibrillary acidic protein in blood: an analytical method.

Background: In the present study, a new assay for the measurement of glial fibrillary acidic protein (GFAP) in human blood is described. The aim of the study was to present the characteristics of a new GFAP assay for blood analysis.

Methods: The method, a newly developed enzyme-linked immunosorbent assay (ELISA), was validated using blood samples from healthy blood donors and from patients with severe traumatic brain injury (TBI).
