The titer corresponds to the highest dilution factor that still yields a positive reading. For example, positive readings in the first 8 serial twofold dilutions translate into a titer of 1:256 (i.e., 2 â8). Titers are sometimes expressed by the denominator only, for example 1:256 is written 256. specific example is a viral titer, which is the lowest concentration of virus that still infects cells. To determine the titer, several dilutions are prepared, such as 10 â1, 10 â2, 10 â3, ...
