Effective July 23, 2026, due to reagent issues, the PP3 (serotype 3) component of the Streptococcus pneumoniae IgG Antibody Panel will not be reported until further notice. Note that an adequate response to pneumococcal vaccination is generally thought to be demonstrated when a patient shows response to at least 50% of the serotypes in the PN23 assay. For most patients, this can be assessed even if only 22 serotypes are reported.
