Intended Use

The Sensititre® Haemophilus influenzae/Streptococcus pneumoniae (HP) MIC Susceptibility plate is an in vitro diagnostic product for clinical susceptibility testing of Haemophilus influenzae; Streptococcus pneumoniae and Streptococcus species.

Device Story

Sensititre® HP MIC Susceptibility plates are in vitro diagnostic tools used in clinical laboratories to determine the minimum inhibitory concentration (MIC) of specific antimicrobial agents against Haemophilus influenzae, Streptococcus pneumoniae, and other Streptococcus species. The device consists of microtiter plates containing dehydrated antimicrobial agents (Gemifloxacin, Linezolid, Levofloxacin) at various concentrations. Clinical laboratory technicians inoculate the plates with patient bacterial isolates; the plates are then incubated. Bacterial growth is observed to determine the MIC, which represents the lowest concentration of an antibiotic that inhibits visible growth. This information is used by healthcare providers to guide antibiotic therapy selection for patients with bacterial infections. The device aids in identifying effective treatments, potentially improving patient outcomes by ensuring appropriate antimicrobial use.

Clinical Evidence

No clinical trials were performed. Evidence consists of in vitro bench testing comparing the Sensititre® MIC results to a reference method. Performance was evaluated by testing clinical isolates of Streptococcus species against Gemifloxacin, Linezolid, and Levofloxacin. Results demonstrated essential agreement and categorical agreement between the Sensititre® system and the reference method, supporting the addition of these organisms to the device's indications.

Technological Characteristics

Microtiter plate format containing dehydrated antimicrobial agents. Principle of operation is broth microdilution for MIC determination. The system is designed for use with the Sensititre® automated or manual reading systems. No specific materials of construction or software algorithms are detailed beyond the standard microdilution methodology.

Indications for Use

Indicated for clinical susceptibility testing of Haemophilus influenzae, Streptococcus pneumoniae, and Streptococcus species. Includes specific testing for Gemifloxacin, Linezolid, and Levofloxacin. Clinical significance established for S. pneumoniae (all drugs), S. pyogenes (Linezolid, Levofloxacin), and S. agalactiae (Linezolid). In vitro data available for other Streptococcus groups (e.g., Viridans, Group C/F/G, S. milleri) with unknown clinical significance.

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.
