The device description and performance studies focus on traditional microbiological methods and do not mention any AI or ML components.
No
The device is used for in vitro diagnostic testing (susceptibility and identification of bacteria), not directly for therapeutic purposes on a patient.
Yes.
The "Intended Use / Indications for Use" section explicitly states that the device is used for "quantitatively measuring... the susceptibility of rapidly growing aerobic and facultative anaerobic bacterial pathogens to a battery of antimicrobial agents and determining the biochemical identification of those organisms." This process of identifying pathogens and assessing their susceptibility to treatments is a diagnostic activity.
No
The device description clearly outlines a physical panel with dispensed antimicrobial agents that are frozen, thawed, inoculated, incubated, and then visually observed for growth or color changes. This involves significant hardware components and manual processes, not just software.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use explicitly states that the panels are used for "quantitatively measuring... the susceptibility of rapidly growing aerobic and facultative anaerobic bacterial pathogens to a battery of antimicrobial agents and determining the biochemical identification of those organisms." This is a classic definition of an in vitro diagnostic test, as it involves analyzing a biological sample (bacterial pathogens) outside of the body to provide information about a disease state (susceptibility to antimicrobial agents).
- Device Description: The description details how the panels are used to test bacterial growth in the presence of antimicrobial agents and interpret biochemical reactions. This process is performed in vitro (in a lab setting).
- Performance Studies: The performance studies involve testing the device against clinical isolates and challenge strains, which are biological samples. The metrics used (Essential Agreement, Category Agreement, errors) are standard for evaluating the performance of IVD devices that determine antimicrobial susceptibility.
Therefore, based on the provided information, the PASCO MIC AND MIC/ID PANELS clearly fit the definition of an In Vitro Diagnostic device.

Intended Use / Indications for Use
Pasco MIC and MIC/ID panels are used for quantitatively measuring (with the exception of the Breakpoint/ID panel which provides qualitative measurement of category results) the susceptibility of rapidly growing aerobic and facultative anaerobic bacterial pathogens to a battery of antimicrobial agents and determining the biochemical identification of those organisms.
This 510(k) notification is for the addition of Clindamycin to Pasco panels at concentrations of 0.015-2 mcg/ml for use in determining the susceptibility of S. pneumoniae and non-pneumococcal streptococci.

Device Description
Varying concentrations of antimicrobial agents (usually in two-fold dilutions) are dispensed into the Pasco panels and the panels are then frozen. Panels are thawed prior to use, inoculated with the test organisms, incubated the traditional 16-24 hours and panels are then observed for visible growth or color changes as described in the package insert. The lowest concentration of each antimicrobial agent with no apparent visible growth of the test organism is recorded as the minimum inhibitory concentration (MIC). Changes in pH and production of specific metabolites from growth in biochemical substrates are interpreted as described in the package insert for conventional tubed media.

Description of the test set, sample size, data source, and annotation protocol
Test panels containing Clindamycin at concentrations ranging from 2-0.015 mcg/ml were prepared in-house at Pasco using routine manufacturing procedures. Comparative testing of the Pasco test panel to a reference panel was performed at two sites using CDC challenge strains and clinical isolates.
Summary of Performance Studies
Test results of the 101 S. pneumoniae strains demonstrated acceptable Essential Agreement (EA) of 90.3%. No major (M), very major (VM) or minor errors were observed. Category agreement (CA) was 100% with 1 random minor error (within EA). Test results of the 130 nonpneumococcal streptococci strains demonstrated acceptable Essential Agreement (EA) of 97.8%. No major (M), very major (VM) or minor errors were observed. Category Agreement (CA) was 100% with no random minor errors. The overall Essential Agreement for streptococci was 93,8%.
QC endpoints for the QC organism S. pneumoniae ATCC 49619 from both the reference and Pasco panels throughout testing were within the recommended NCCLS acceptable range.
Reproducibility testing of 12 organisms at each site provided 7 organisms with on-scale endpoints. Overall reproducibility data demonstrated 100% within the acceptable plus or minus 1 dilution.
The results of the clinical testing, reproducibility testing and OC performance testing supports Substantial Equivalence as outlined in the FDA draft document "Review Criteria For Assessment Of Antimicrobial Susceptibility Devices" (May 1991).

SUBSTANTIAL EQUIVALENCE:
In review of previous 510(k) notifications for the Pasco MIC and MIC/ID panels (most recently: K982235, July 30, 1998 RE: Minocycline; K982156, July 29, 1998 RE: Cefdinir; K980955 May 18, 1998 RE: Trovafloxacin; K974362, February 12, 1998 RE: Cefepime; K973317, November 14, 1997 RE: Cefpodoxime: K973695, November 5, 1997 RE: Meropenem; K972567, August 20,1997 RE: Sparfloxacin: K971951. August 15, 1997 RE: Levofloxacin: and K946126, January 17, 1995 RE: Detection of resistant pneumococci), the FDA has determined the Pasco panels to be substantially equivalent to devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments.
The term "substantial equivalence" as used in this 510(k) notification is limited to the definition of substantial equivalence as found in the Federal Food, Drug, and Cosmetic Act, as amended and as applied under 21 CFR 807, Subpart E under which a device can be marketed without pre-market approval or reclassification. A determination of substantial equivalency under this notification is not intended to have any bearing whatsoever on the resolution of patent infringement suits or any other patent matters. No statements related to, or in support of substantial equivalence herein shall be construed as an admission against interest under the US Patent Laws or their application by the courts.
DESCRIPTION OF THE DEVICE:
Varying concentrations of antimicrobial agents (usually in two-fold dilutions) are dispensed into the Pasco panels and the panels are then frozen. Panels are thawed prior to use, inoculated with the test organisms, incubated the traditional 16-24 hours and panels are then observed for visible growth or color changes as described in the package insert.

The lowest concentration of each antimicrobial agent with no apparent visible growth of the test organism is recorded as the minimum inhibitory concentration (MIC). Changes in pH and production of specific metabolites from growth in biochemical substrates are interpreted as described in the package insert for conventional tubed media.
INTENDED USE FOR THE PASCO MIC AND MIC/ID PANELS:
PASCO MIC AND MIC/ID PANELS are used for quantitatively measuring (with the exception of the Breakpoint/D panel which provides qualitative measurement or category results) the susceptibility of rapidly growing aerobic and facultative anaerobic bacterial pathogens to a battery of antimicrobial agents and determining the biochemical identification of those organisms.
SUMMARY/CONCLUSION OF SUBSTANTIAL EQUIVALENCE TESTING:
Test panels containing Clindamycin at concentrations ranging from 2-0.015 mcg/ml were prepared in-house at Pasco using routine manufacturing procedures. Comparative testing of the Pasco test panel to a reference panel was performed at two sites using CDC challenge strains and clinical isolates.
Test results of the 101 S. pneumoniae strains demonstrated acceptable Essential Agreement (EA) of 90.3%. No major (M), very major (VM) or minor errors were observed. Category agreement (CA) was 100% with 1 random minor error (within EA). Test results of the 130 nonpneumococcal streptococci strains demonstrated acceptable Essential Agreement (EA) of 97.8%. No major (M), very major (VM) or minor errors were observed. Category Agreement (CA) was 100% with no random minor errors. The overall Essential Agreement for streptococci was 93,8%.
QC endpoints for the QC organism S. pneumoniae ATCC 49619 from both the reference and Pasco panels throughout testing were within the recommended NCCLS acceptable range.
Reproducibility testing of 12 organisms at each site provided 7 organisms with on-scale endpoints. Overall reproducibility data demonstrated 100% within the acceptable plus or minus 1 dilution.
The results of the clinical testing, reproducibility testing and OC performance testing supports Substantial Equivalence as outlined in the FDA draft document "Review Criteria For Assessment Of Antimicrobial Susceptibility Devices" (May 1991).
