Intended Use
The Liofilchem® MIC Test Strip (MTS) is a quantitative method intended for the in vitro determination of antimicrobial susceptibility of bacteria. MTS consists of specialized paper impregnated with a pre-defined concentration gradient of an antimicrobial agent, which is used to determine inhibitory concentration (MC) in ug/mL of antimicrobial agents against bacteria as tested on agar media using overnight incubation and manual reading procedures. The Meropenen-vaborbactam MTS at concentrations of 0.016/8 - 2568 ug/mL should be interpreted at 16-20 hours of incubation. Meropenem-vaborbactam has been shown to be active both clinically and in vitro against the non-fastidious bacteria listed below according to the FDA label: Enterobacter cloacae species complex Escherichia coli Klebsiella pneumoniae Meropenem/vaborbactam has been shown to be active in vitro against susceptible isolates of the following microorganisms: Citrobacter freundii Citrobacter koseri Enterobacter aerogenes Klebsiella oxytoca Proteus mirabilis Providencia spp. Serratia marcescens

No
The description details a manual, paper-based method for determining antimicrobial susceptibility, with no mention of automated analysis, image processing, or any terms related to AI/ML.

No
This device is an in vitro diagnostic (IVD) tool used to determine the antimicrobial susceptibility of bacteria, not to treat a condition or disease in a patient.

Yes

The device determines the minimum inhibitory concentration (MIC) of antimicrobial agents against bacteria, which is used to assess antimicrobial susceptibility. This information is crucial for guiding treatment decisions and is a form of in vitro diagnostic testing.

No

The device description explicitly states it consists of "specialized paper impregnated with a pre-defined concentration gradient of an antimicrobial agent," indicating a physical, hardware component.

Yes, this device is an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The "Intended Use / Indications for Use" section explicitly states that the device is "intended for the in vitro determination of antimicrobial susceptibility of bacteria." "In vitro" means "in glass" or "in the lab," referring to tests performed outside of a living organism.
  • Purpose: The device is used to determine the minimum inhibitory concentration (MIC) of antimicrobial agents against bacteria. This is a diagnostic test to assess how effectively an antibiotic will work against a specific bacterial infection.
  • Sample Type: The test is performed on bacteria grown on agar media, which is a laboratory sample, not a sample taken directly from a patient's body for immediate analysis within the body.

Therefore, based on the provided text, the Liofilchem® MIC Test Strip (MTS) clearly fits the definition of an In Vitro Diagnostic device.

Dear Anne Windau:

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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
