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, ...
Be age 65 or older and eligible for Social Security: You may be automatically enrolled into Medicare Part A (hospital insurance) when you reach age 65 and become eligible for Social Security; but if you want Medicare Part B (medical insurance), you have to enroll in it.
