Indications for Use

The Binax NOW Streptococcus pneumoniae Test is an in vitro rapid immunochromatographic detection of assay for the (ICT) Streptococcus pneumoniae (S. pneumoniae) antigen in the urine of patients with pneumonia and in the cerebral spinal fluid (CSF) of patients with meningitis. It is intended, in conjunction with culture and other methods, to aid in the presumptive diagnosis of both pneumococcal pneumonia and pneumococcal meningitis.

Device Story

Immunochromatographic membrane assay; detects pneumococcal soluble antigen in human urine and CSF. Device consists of hinged, book-shaped test card containing a test strip with rabbit anti-S. pneumoniae antibody (sample line) and control antibody (control line) adsorbed onto nitrocellulose membrane. Sample collected via swab; inserted into device; buffer reagent added. Device closed to initiate flow. Antigen binds to antibody-conjugated particles; complexes captured by immobilized antibodies on membrane. Visual result interpretation within 15 minutes. Used in clinical settings by healthcare professionals. Provides rapid presumptive diagnosis to supplement culture methods; facilitates timely clinical decision-making for patients with suspected pneumonia or meningitis.

Clinical Evidence

No clinical data presented for the urine application (previously cleared under K991762). Performance for CSF application was evaluated using freshly collected CSF specimens.

Technological Characteristics

Immunochromatographic membrane assay. Components: nitrocellulose membrane, rabbit anti-S. pneumoniae antibody, colloidal gold conjugate, fibrous support pad. Form factor: hinged, book-shaped test card. Visual readout. No electronic components or software.

Indications for Use

Indicated for the detection of S. pneumoniae antigen in urine of patients with pneumonia and CSF of patients with meningitis to aid in presumptive diagnosis. For prescription use.

Regulatory Classification

Identification

Streptococcus spp. serological reagents are devices that consist of antigens and antisera (excluding streptococcal exoenzyme reagents made from enzymes secreted by streptococci) used in serological tests to identify Streptococcus spp. from cultured isolates derived from clinical specimens. The identification aids in the diagnosis of diseases caused by bacteria belonging to the genus Streptococcus and provides epidemiological information on these diseases. Pathogenic streptococci are associated with infections, such as sore throat, impetigo (an infection characterized by small pustules on the skin), urinary tract infections, rheumatic fever, and kidney disease.

- The Binax NOW Streptococcus pneumoniae Test Device Description: is an immunochromatographic membrane assay used to detect pneumococcal soluble antigen in human urine and CSF. Rabbit anti-S. pneumoniae antibody, the Sample Line, is membrane. nictrocellulose adsorbed onto Control antibody is adsorbed onto the same membrane as a second stripe. Both rabbit pneumoniae anti-S. and and anti-species antibodies are conjugated to visualizing are dried onto an inert particles that The resulting conjugate fibrous support. pad and striped membrane are combined to construct the test strip.

The Binax NOW Streptococcus pneumoniae Test is an in vitro rapid immunochromatographic detection of assay for the (ICT) Streptococcus pneumoniae (S. pneumoniae) antigen in the urine of patients with pneumonia and in the cerebral spinal fluid (CSF) of patients with meningitis. It is intended, in conjunction with culture and other methods, to aid in the presumptive diagnosis of both pneumococcal pneumonia and pneumococcal meningitis.

Both the Binax NOW® Streptococcus pneumoniae and the Wellcogen Bacterial Antigen Tests Characteristics: are simple rapid tests with a visual result interpretation. Both use a solid phase coated with polyclonal antibody to detect S. pneumoniae in human urine and CSF samples. However, the predicate device is a latex agglutination test employing antibody coated polystyrene beads that agglutinate in the presence of sufficient homologous antigen. The Binax NOW Streptococcus pneumoniae Test is an immunochromatographic assay utilizing a colloidal gold conjugate and an antibody striped membrane to capture and visualize antigen.

The Binax NOW Streptococcus pneumoniae Test Performance Summary: is substantially equivalent to the predicate device, the Wellcogen Bacterial Antigen Test of ટ . detection (K854852), for the pneumoniae antigen in urine and CSF. The Binax NOW Streptococcus pneumoniae Test has diqanosis already been cleared for of pneumonia using a urine specimen (510(k) number K991762). No new data for the urine application is presented here. This
