Detection of poliovirus antibodies due to immunization or previous exposure to polio or other enteroviruses. Cross-reaction with other enteroviruses are known. Less than 2% of tested individuals have less than 1:8 titer. If an acute polio infection is suspected, paired sera samples, at least three weeks apart, would demonstrate at minimum, a four-fold rise in titer. Best indication of immunity to poliovirus is the neutralization antibody test.
