Used for diagnostic evaluation of pneumococcal immunity, epidemiological studies of serotype-specific colonization or infection, and verification of vaccine responses to S. pneumoniae type 7f.
The purified capsular polysaccharide antigen stimulates a localized immune response upon intradermal administration or triggers antibody detection in serology tests, indicating prior exposure or immunity to the specific pneumococcal serotype.
This is a diagnostic antigen, not a therapeutic agent or vaccine. Should only be administered by healthcare professionals trained in skin testing procedures. Interpretation requires clinical context and may need confirmation with additional laboratory testing.
