Device Facts

• Record ID: K040846
• Device Name: SENSITITRE HAEMOPHILUS/STREPTOCOCCUS PNEUMONIAE (HP) MIC PLATES
• Applicant: Trek Diagnostic Systems, Inc.
• Product Code: JWY · Microbiology
• Decision Date: Apr 26, 2004
• Decision: SESE
• Submission Type: Traditional
• Regulation: 21 CFR 866.1640
• Device Class: Class 2

Intended Use

The Sensititre® Haemophilus/Streptococcus pneumoniae (HP) MIC plates are in vitro diagnostic product for clinical susceptibility testing of Haemophilus influenzae and Streptococcus pneumoniae. This will include ertapenem in the dilution range of 0.008 - 16 ug/mL to the Sensititre® Haemophilus/Streptococcus pneumoniae (HP) MIC susceptibility plate for testing Haemophilus influenzae and Streptococcus pneumoniae isolates.

Device Story

Sensititre® HP MIC plates are multi-well plastic microtitre plates containing dried, stabilized antimicrobics for broth microdilution susceptibility testing. Inoculum prepared in Haemophilus Test medium (H. influenzae) or 2–5% lysed horse blood (S. pneumoniae). Plates are sealed, incubated at 34–36°C for 20–24 hours. Growth is detected via fluorescence (automated) or turbidity (manual). Automated reading uses Sensititre® AutoReader® or ARIS®; manual reading uses viewer or SensiTouch®. Output is Minimum Inhibitory Concentration (MIC) and categorical interpretation (SIR). Used in clinical microbiology laboratories to guide antibiotic therapy decisions for patients with H. influenzae or S. pneumoniae infections.

Clinical Evidence

No clinical data provided. The submission relies on in vitro data demonstrating the performance of the Sensititre HP MIC Susceptibility plate for Ertapenem testing against specified bacterial strains.

Technological Characteristics

Multi-well plastic microtitre plates; dried, stabilized antimicrobics. Sensing principle: fluorescence detection of bacterial growth (automated) or visual turbidity (manual). Energy source: electrical (for automated readers). Connectivity: standalone or networked (ARIS®). Sterilization: not specified. Software: automated growth detection algorithm.

Indications for Use

Indicated for clinical susceptibility testing of H. influenzae and S. pneumoniae isolates. Specifically for Ertapenem testing: S. pneumoniae (penicillin-susceptible strains) and H. influenzae (beta-lactamase negative strains). In vitro data provided for S. pneumoniae (penicillin-intermediate strains) and H. influenzae (beta-lactamase positive strains).

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.

## Dear Ms. Knapp:

This letter corrects our substantially equivalent letter of April 26, 2004, regarding the change of address.

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found i Title 21, Code of Federal Regulations (CFR), Parts 800 to 895. In addition, FDA may publish further announcements concerning your device in the Federal Register.
