Beta-2-Transferrin, Ear or Nasal Fluid


Reference Range

Beta-2-transferrin is a carbohydrate-free isoform of transferrin, which is almost only found in the cerebrospinal fluid (CSF), thus making it a specific marker of cerebrospinal fluid. This test is performed in cases where CSF leakage is suspected. A POSITIVE result therefore indicates CSF leakage, or as well a perilymph leak.
