Clinical Use: CSF Rhinorrhoea testing is used to determine whether a fluid leaking from the nose or mouth as a result of trauma is CSF arising from damage to the membranes covering the brain.
Background: Tau protein (beta-transferrin), a constituent of CSF, is not normally found in blood, nasal secretions or other bodily fluids. Consequently its presence or absence indicates the type of fluid involved, its source and an idea of the seriousness of the injury.
