Serum antibody titers

WebAntibody titer is an assay-specific measurement. One immunization protocol, for example, may produce an antibody titer of 1:10000 dilution, while a second protocol may produce an antibody titer of only 1:5000. Alternatively, one bleed of antiserum may have a high titer compared to a second bleed of antiserum tested in the same assay. WebPolio 1 Titer: <1:8. Polio 3 Titer: <1:8 . The presence of neutralizing serum antibodies (titers 1:8 up to >1:128) against polioviruses implies lifelong immunity. Some persons without detectable titers (<1:8) may also be immune as demonstrated by elicitation of a secondary-type serum antibody response upon rechallenge with live polio vaccine.
