Assessment of a rapid urinary antigen detection by an immunochromatographic test for diagnosis of pneumococcal infection in children.

The aim of the study was to evaluate the Binax Now rapid immunochromatographic test (ICT) for the detection of Streptococcus pneumoniae urinary antigen in children suffering from potentially pneumococcal infections. A total of 287 patients, with a median age of 34.9 months and divided into 3 groups, were studied; the first group of patients with a suspected pneumococcal infection (n = 112), the second group with infectious symptoms nonsuggestive of a pneumococcal infection (n = 54), and the third group was composed of asymptomatic children (n = 121).

[Rapid identification of pneumococcal antigenes in urines by the Now Streptococcus pneumoniae Binax test].

Streptococcus pneumoniae is responsible for many infectious conditions but probably with an underestimated incidence especially because of the fragility of the bacteria. The present study has evaluated a new test which detects a pneumococcal antigen in urine (Now S.p Binax).
