No
The device description and performance studies describe a traditional, manual method for determining MIC and identification based on visual observation of growth and color changes. There is no mention of automated analysis, algorithms, or learning processes.
No
The device is used for in vitro diagnostic testing to determine antimicrobial susceptibility and biochemical identification of bacteria, not for treating a disease or condition in a patient.
Yes
The device is used for quantitatively measuring the susceptibility of bacterial pathogens to antimicrobial agents and determining their biochemical identification, which directly aids in diagnosing infections and guiding treatment.
No
The device description explicitly states that the device involves physical panels containing antimicrobial agents and requires incubation and observation for visible growth or color changes. This indicates a hardware component (the panels) and a physical process, not a software-only device.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use 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 is performed in vitro (outside of the living body) on biological samples (bacterial pathogens).
- Device Description: The description details how the panels are used to test bacterial growth in the presence of antimicrobial agents and observe biochemical changes. This is a classic method for in vitro diagnostic testing in microbiology.
- Performance Studies: The performance studies involve testing the device against reference methods using bacterial isolates, further confirming its use in a laboratory setting for diagnostic purposes.
The core function of the device is to provide information about a biological sample (bacterial susceptibility and identification) that is used for diagnostic purposes. This aligns directly with 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 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.
This 510(k) notification is for the addition of the antimicrobial Linezolid at concentrations of 0.25 - 8 mcg/ml to Pasco Panels. Linezolid has been shown to be active in vitro against most strains of microorganisms listed below, as described in the FDA-approved package insert for this antimicrobic.
Active In Vitro and in Clinical Infectious Against:
Aerobic Gram-positive microorganisms
Enterococcus faecium (vancomycin-resistant strains only) Staphylococcus aureus (including methicillin-resistant strains)
Active In Vitro but their clinical significance is unknown
Aerobic Gram-positive microorganisms
Enterococcus faecalis (including vancomycin-resistant strains) Enterococcus faecium (vancomycin-susceptible strains) Staphylococcus epidermidis (including methicillin-resistant strains) Staphylococcus haemolyticus

Device Description
Pasco 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. Varying concentrations of antimicrobial agents (usually in two-fold dilutions) are dispensed into the Pasco microdilution 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.

Challenge strains, fresh clinical isolates, stock clinical isolates and QC strains were tested concurrently using both Pasco methodology and reference methodology in panels contained Linezolid at concentrations ranging from 0.25 - 8 mcg/ml. Testing was conducted at three test sites.
Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Test results of 413 challenge and clinical Staphylococcus spp. and 365 challenge and clinical Enterococcus spp. demonstrated an Essential Agreement (EA) of 99.9%. Category agreement (CA) was 100% with no very major (VM), major (M) or minor errors observed.
QC endpoints for the NCCLS recommended OC organisms (S. aureus ATCC 29213 and E. faecalis ATCC 29212) from panels using both the reference and test methodology were acceptable.
Reproducibility testing of 10 organisms at each site on three separate days in triplicate demonstrated inter-site reproducibility of MIC results of 100%. Intra-site reproducibility of MIC results was 100% for all sites as well.
The results of the clinical testing, reproducibility testing and QC performance testing supports Substantial Equivalence as outlined in the FDA document "Class II Special Controls Guidance Document: Antimicrobial Susceptibility Test (AST) Systems; Guidance for Industry and FDA.
Key Metrics (Sensitivity, Specificity, PPV, NPV, etc.)
