Factor VIII R:Ag as a prognostic parameter in intracranial haemorrhage

Factor VIII R:Ag was measured serially in 42 patients who had intracranial haemorrhage. It was found that the factor decreased or remained static in the 24 patients who improved (p less than 0.025), while it increased in the 18 who died (p less than 0.0005). It is suggested that this factor can be used as a prognostic parameter to predict the outcome after intracranial haemorrhage.
