LAB205
Collect
Aural or nasal fluid in sterile container.
Specimen Preparation
Do not freeze. Transport 2 mL aural or nasal fluid in a tube without preservative. (Min: 1 mL aural or nasal fluid)
Storage/Transport Temperature
Refrigerated.
Stability (from collection to initiation)
Ambient: 4 hours; Refrigerated: 72 hours; Frozen: Unacceptable
Notes
The beta-2 transferrin protein assay by IFE methodology is not a reliable method for detecting human perilymph due to the low sensitivity of the assay.
Performed
Sun-Sat
Methodology
Qualitative Immunofixation Electrophoresis
Reported
1-4 days
Synonyms
- Transferrin, Beta-2
- LAB205
- B2TRNSF
Ordering Recommendations
Aids in diagnosis of CSF leak.
Reference Interval
None detected
Interpretive Data
Detection of a beta-2 transferrin band by IFE is diagnostic for the presence of cerebrospinal fluid (CSF). This test is useful in the differential diagnosis for CSF otorrhea or CSF rhinorrhea. Beta-2 transferrin is not detected by this methodology in normal serum, tears, saliva, sputum, nasal, or aural fluid.
