33557 - Pneumococcal Antibody Panel - PPSV23 (23 Serotype)
Eurofins Viracor’s new pneumococcal antibody panels are designed to meet CDC recommendations by targeting all serotypes included in the currently approved pneumococcal vaccines—PCV15, PCV20, PPSV23, and the recently approved PCV21—providing comprehensive coverage for clinical assessment of immune response (Centers for Disease Control and Prevention, 2024)
Eurofins Viracor’s pneumococcal antibody panel provides quantitative measurement of serotype-specific IgG antibodies to assess immune response to pneumococcal vaccination, particularly in immunocompromised patients.
About Pneumococcal Antibody Testing
Pneumococcal antibody testing designed for PPSV23 evaluates immune response to the 23 serotypes included in the vaccine (1, 2, 3, 4, 5, 6B, 7F, 8, 9N, 9V, 10A, 11A, 12F, 14, 15B, 17F, 18C, 19A, 19F, 20A, 22F, 23F, and 33F) This testing is clinically important for assessing protection against invasive pneumococcal disease, particularly in individuals at increased risk.21 The serotype coverage included in this testing enhances the panel's ability to evaluate protective immunity across a broader spectrum of pneumococcal strains.
Multiplex fluorescent immunoassay using beads coupled with capsular polysaccharide antigens corresponding to the analyzed Streptococcus pneumoniae serotypes present in the available vaccines. The assay is calibrated to international reference material to ensure accuracy. This test was developed and its performance characteristics determined by Eurofins Viracor. It has not been cleared or approved by the U.S. Food and Drug Administration.
