How to interpret titers
WebWhile individual serum and CSF titers can be determined, the ratio of serum:CSF titers is very predictive of an EPM diagnosis. As intrathecal IgG production increases, the titer ratio decreases and ratios of <100 strongly correlate with EPM. A <100 ratio has a sensitivity = 83% and a specificity = 97%. WebAs with pattern interpretation, an estimated titer can be replaced with a titer from serial dilutions, depending on the pattern and the technologist’s judgment. Overall, although not completely automated by chemistry standards, the availability of automation for IIF, EIA, and MIA gives labs several options for complex ANA testing in a time of shrinking resources.
