How would you test S.B. for evidence of cerebrospinal fluid (CSF) leakage?
What will be an ideal response?
• If there is evidence of clear drainage from the ear or nasal cavities, a reagent strip can be used to
confirm the presence of glucose—a positive indicator of CSF.
• If the drainage is bloody or pink-tinged, a drop of the fluid can be placed on a piece of linen
or gauze. If a light outer ring forms around a dark inner ring (positive halo sign), the drainage
contains CSF.
