Intended Use
The MicroScan Prompt® Inoculation System-D is used to standardize inocula for microdilution antimicrobial susceptibility tests. The MicroScan Prompt Inoculation System-D is an accessory to the MicroScan Gram Negative and Gram Positive MIC/Combo Panels. Indications for use organisms are specific for each antimicrobial agent on the panel.
Device Description
The MicroScan Prompt Inoculation System-D is a method for obtaining standardized bacterial inoculum while eliminating the need for incubation and turbidity adjustment with inocula prepared according to the CLSI procedure. It consists of an inoculation wand and a bottle of diluent. The wand is a polypropylene rod with a breakaway collar that serves as a wiping mechanism. The rod is attached to a stopper. At the tip of the wand is a groove designed to hold a specific amount of bacteria equivalent to a 0.5 McFarland standard. Thirty (30) ml of diluent (Pluronic is used as the surfactant) are provided in the plastic bottle. Each kit contains 60 plastic bottles, each containing 30 ml of stabilized aqueous Pluronic surfactants and 62 inoculation wands.
More Information

Not Found

No
The device description and performance studies focus on a physical inoculation method and its equivalence to a standard turbidity method, with no mention of AI or ML algorithms for analysis or interpretation.

No
The device is described as an accessory used to standardize inocula for antimicrobial susceptibility tests, not to treat or prevent disease.

No

The device is described as a system used to standardize inocula for antimicrobial susceptibility tests, acting as an accessory to MicroScan panels. Its function is to prepare samples for testing, not to perform diagnosis itself.

No

The device description explicitly states it consists of an inoculation wand and a bottle of diluent, which are physical components, not software.

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

Here's why:

  • Intended Use: The intended use explicitly states it is used to "standardize inocula for microdilution antimicrobial susceptibility tests." Antimicrobial susceptibility testing is a laboratory test performed on biological samples (bacteria) to determine their sensitivity to various antimicrobial agents. This falls squarely within the definition of an in vitro diagnostic test.
  • Device Description: The device is designed to prepare a standardized bacterial inoculum, which is a crucial step in performing in vitro diagnostic tests for antimicrobial susceptibility.
  • Accessory to IVD Panels: It is described as an "accessory to the MicroScan Gram Negative and Gram Positive MIC/Combo Panels." These panels are themselves IVD devices used for antimicrobial susceptibility testing. An accessory specifically designed for use with an IVD device is typically considered an IVD itself or an IVD accessory.
  • Performance Studies: The performance studies described involve evaluating the device's performance in the context of antimicrobial susceptibility testing, comparing it to established methods (CLSI broth microdilution reference method) and analyzing results based on guidelines for AST (Antimicrobial Susceptibility Test) systems. This further reinforces its role in an in vitro diagnostic process.
  • Predicate Device: The predicate device listed is the "3M Prompt Inoculation System," which is also an inoculation system used for similar purposes in antimicrobial susceptibility testing, indicating a history of such devices being regulated as IVDs.

Based on the intended use, device description, its role as an accessory to other IVD panels, and the context of the performance studies, the MicroScan Prompt® Inoculation System-D is clearly an In Vitro Diagnostic device.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Clinical performance data obtained with the Prompt Inoculation System-D were evaluated in previously conducted studies described in recent 510(k) decision summaries for the MicroScan Dried Gram negative and Gram positive MIC/Combo panels for each antimicrobial agent.

Performance of the MicroScan MIC/Combo panels were evaluated using the Prompt inoculation method and the turbidity method against the CLSI broth microdilution reference method and results were analyzed based on the recommended guidelines in the AST Class II Special Controls Guidance Document issued on August 28, 2009. Any antimicrobial agent specific performance notes or limitations are included in the applicable MicroScan MIC/Combo Panel procedural manual.

INTENDED USE

The MicroScan Prompt® Inoculation System-D is used to standardize inocula for microdilution antimicrobial susceptibility tests.

The MicroScan Prompt Inoculation System-D is an accessory to the MicroScan Gram Negative and Gram Positive MIC/Combo Panels. Indications for use organisms are specific for each antimicrobial agent on the panel.

Device Description:

The MicroScan Prompt Inoculation System-D is a method for obtaining standardized bacterial inoculum while eliminating the need for incubation and turbidity adjustment with inocula prepared according to the CLSI procedure. It consists of an inoculation wand and a bottle of diluent. The wand is a polypropylene rod with a breakaway collar that serves as a wiping mechanism. The rod is attached to a stopper. At the tip of the wand is a groove designed to hold a specific amount of bacteria equivalent to a 0.5 McFarland standard. Thirty (30) ml of diluent (Pluronic is used as the surfactant) are provided in the plastic bottle. Each kit contains 60 plastic bottles, each containing 30 ml of stabilized aqueous Pluronic surfactants and 62 inoculation wands.

Principle of Operations:

The MicroScan Prompt Inoculation System-D is an in vitro accessory which aids in the inoculum proparation for use with MicroSan Dried Gram positive and/or Gram negative MIC/Combo panels for quantitative and qualitative antimicrobial susceptibility testing.

The MicroScan Prompt Inoculation System-D wand is touched to several bacterial colonies on a primary isolation plate, wiped, then placed in the plastic bottle. The bacteria are suspended by shaking the bottle. The bacterial suspension, which is equivalent to a 0.5 McFarland, is stable for four hours after preparation.

Comparison with the Predicate(s):

The MicroScan Prompt Inoculation System-D is substantial equivalent to the predicate device. Refer to Substantial Equivalence Table below.
