CerTest S. pneumoniae one step card test is a coloured chromatographic immunoassay for the qualitative detection of Streptococcus pneumoniae in human urine samples.

CerTest S. pneumoniae card test offers a highly sensitive and simple screening assay to make a presumptive diagnosis of pneumoniae caused by Streptococcus pneumoniae in infected humans.

Gram positive bacteria, Streptococcus pneumoniae is one of the most important pathogen that affects mainly children and elderly and can cause life-threatening diseases.

Streptococcus pneumoniae infection leads to many clinical manifestations including meningitis, septicaemia, bacteraemia, pneumonia, acute otitis media, and sinusitis. It has caused great mobility and mortality worldwide, especially in children.

Pneumococcal infection annually has caused approximately 14.5 million cases of invasive pneumococcal disease (IPD) and 0.7–1 million deaths in children under five years old, mostly in developing and underdeveloped countries.

Based on differences in the polysaccharide capsules of the pneumococcal cell wall, Streptococcus pneumoniae is classified into over 90 serotypes, which present different antigenic properties and induce different inflammatory responses. The CerTest Streptococcus pneumoniae allows for early diagnosis of Streptococcus pneumoniae infection through detection of a specific soluble antigen present in the urine of patients with Streptococcus pneumoniae infection. Streptococcus pneumoniae cell wall polysaccharide antigen has been detected in urine as early as three days after the onset of symptoms.

The test is rapid, giving a result in 15 minutes, and utilizes a urine specimen which is convenient for collection, transport, and subsequent detection of early, as well as later, stages of disease.
