Characterisation of the Diagnostic Window of Serum Glial Fibrillary Acidic Protein for the Differentiation of Intracerebral Haemorrhage and Ischaemic Stroke

Abstract

The time window between 2 and 6 h after stroke onset is best for using GFAP to differentiate between ICH and IS. In the very early phase (i.e. <2 h), sensitivity for detecting ICH is low, thus hampering the application of GFAP as a near-patient test in the prehospital phase.
