Test Code PN23M Streptococcus pneumoniae IgG Antibodies, 23 Serotypes, Serum


Ordering Guidance


This test is the preferred test for patients previously tested for Streptococcus pneumoniae serotypes (as part of follow up testing or part of pre/post vaccine assessment).

 

The preferred test for patients being evaluated for possible immunodeficiency or for assessment of pneumococcal vaccination response (initial evaluation) is PNTOR / Streptococcus pneumoniae IgG Antibodies, Total, with Reflex, Serum

 

The preferred test for patients previously tested for total Streptococcus pneumoniae antibodies (as part of follow up testing or part of pre/post vaccine assessment) is PNTO / Streptococcus pneumoniae IgG Antibodies, Total, Serum

Interpretation

As a general guideline, nonimmunocompromised adults develop IgG antibodies approximately 4 to 6 weeks following nonconjugated vaccination.

 

Either of the following conditions is consistent with a normal response to Streptococcus pneumonia vaccination:

1. When comparing pre- and post-vaccination samples, antibody concentrations increased by at least 2-fold for

a. >50% of serotypes in children <6 years of age

b. >70% of serotypes for individuals >6 years of age

 

2. In either a pre- or post-vaccination sample, antibody concentrations >/= 1.0 mcg/mL for

a. >50% of serotypes for children <6 years of age

b. >70% of serotypes for individuals >6 years of age

Day(s) Performed
