Intended Use

The Sensititre Haemophilus influenzae/Streptococcus pneumoniae plates are in vitro diagnostic products for clinical susceptibility testing of Haemophilus influenzae, Streptococcus pneumoniae and Streptococcus species. Sensititie® Haemophilus influenzae/Streptococcus pneumoniae (HP) MIC Susceptibility Plates with Dtest (containing erythromycin at 1 µg/ml and clindamycin at 0.5µg/ml) broth test for Streptococcus pneumoniae and Streptococus spp.-9-Hemolytic Group is an in vitro diagnostic product for clinical susceptibility testing. The Dtest for broth microdilution test is for manual read detection of inducible clindamycin resistance in Streptococcus pyogenes and Streptococcus agalactiae resistant to erythromycin (MICs ≥ 1 µg/mL) and susceptible or intermediate to clindamycin (MICs ≤ 0.25 µg/mL or 0.5 µg/mL), and to determine absence of inducible clindamycin resistance in Streptococus pneumoniae. The performance of this test for the detection of inducible clindamycin resistance in isolates of S. pneumoniae has not been established. With S. pyogenes and S. agalactiae, a Dtest (1/0.5 ug/ml) positive (growth) test, determined by manual read, should be reported as inducible clindamycin resistance.

Device Story

Sensititre HP MIC Susceptibility Plates are in vitro diagnostic tools for clinical microbiology laboratories. The device utilizes broth microdilution to determine minimum inhibitory concentrations (MIC) of antimicrobial agents. The Dtest component, containing erythromycin (1 µg/mL) and clindamycin (0.5 µg/mL), is used to detect inducible clindamycin resistance in specific Streptococcus species. Laboratory technicians perform manual reads of the plates to identify growth, which indicates inducible resistance. Results assist clinicians in selecting appropriate antibiotic therapies for patients with bacterial infections. The device provides standardized susceptibility data to guide clinical decision-making and improve patient outcomes.

Clinical Evidence

No clinical data provided. The submission relies on bench testing for the performance of the broth microdilution and Dtest methodology for susceptibility testing.

Technological Characteristics

Broth microdilution susceptibility plates containing antimicrobial agents (erythromycin and clindamycin). Manual read format. In vitro diagnostic use.

Indications for Use

Indicated for clinical susceptibility testing of Haemophilus influenzae, Streptococcus pneumoniae, and Streptococcus species (including S. pyogenes and S. agalactiae). Specifically used for manual detection of inducible clindamycin resistance in erythromycin-resistant, clindamycin-susceptible/intermediate S. pyogenes and S. agalactiae. Performance for inducible clindamycin resistance in S. pneumoniae is not established.

Regulatory Classification

Identification

An antimicrobial susceptibility test powder is a device that consists of an antimicrobial drug powder packaged in vials in specified amounts and intended for use in clinical laboratories for determining in vitro susceptibility of bacterial pathogens to these therapeutic agents. Test results are used to determine the antimicrobial agent of choice in the treatment of bacterial diseases.
