WebMar 1, 2004 · β 2-Transferrin, the asialo form of transferrin, is produced by neuraminidase activity in the brain and is usually detectable only in CSF, perilymph, and aqueous humor. Thus, like β-trace protein, it is a potentially useful marker to diagnose CSF leakage ( 3 ). WebCSF leakage can be seen on scans but if doubt remains then a useful test is detection of beta-2 transferrin (also known as asialotransferrin or tau protein) β-2-transferrin is a carbohydrate-free (desialated) form of transferrin, almost exclusively found in the CSF, and detection of this protein can confirm a suspected CSF leak. ...

WebQuest test code 10640. B2TRF. Clinical significance: The presence of Beta-2 Transferrin in nasal or ear fluid, or in wound drainage following head trauma, surgery or from tumors or congenital malformation, clearly indicates CSF leaking into these passages or fluids creating a pathway for life-threatening central nervous system infection. WebBeta-2 transferrin is the most reliable confirmatory test for CSF leak. High-resolution CT (HRCT) is then recommended as the first-line study for localization. Magnetic resonance cisternography (MRC) should be used for CSF leak identification as a second line for each of these if beta-2 transferrin is not available or if HRCT is ambiguous. chiss home world
