The virus titer estimates by the viable cell diameter method is close to the plaque assay-based estimates, although the cell diameter method may overestimate the titer by threefold relative to the plaque assay method. However, this is not surprising given that the two methods use different methodologies.n this method, the Vi-CELL (Beckman Coulter) was used to measure cell diameter change over a range of virus dilutions, following infection. The cell diameter change data were used to compute the virus titer using a statistical method called the method of moments that we have described previously.
The result of this test can be expressed in two ways: as a Rabies virus neutralizing antibodies (RVNA) endpoint titer (e.g., 1:50) or as a value for RVNA potency (e.g., 0.5 IU). The IU stands for international unit and is calculated from the titer by comparing it against the titer of a standard reference serum.herefore the calculation of IU/mL depends on the titer of the reference serum measured in the batch tested. In general, you can take the titer value divided by 100 to get a rough estimate of the IU/mL value. To obtain the exact value you must use the calculation with the measured reference serum titer value.
