Intended Use
The COULTER GEN S System with IRF and MRV Parameters is a quantitative, automated hematology analyzer and leukocyte differential counter For In Vitro Diagnostic Use in clinical laboratories. The COULTER GEN-S System also provides automated Reticulocyte analysis. An automated differential cell counter is a device used to identify and classify one or more of the formed elements of blood.
Device Description
The Immature Reticulocyte Fraction expresses the number of early reticulocytes as a proportion of the total reticulocyte count. Mean reticulocyte volume (MRV) is the average cell volume of the reticulocytes, determined by the VCS Technology algorithm and is reported in femtoliters (fL). This 510(k) Premarket Notification provides information demonstrating that Coulter hematology analyzers with IRF and MRV parameters are substantially equivalent to products previously cleared for this use. The COULTER hematology analyzers with IRF and MRV parameters are compared to Sysmex™ hematology analyzers with the IRF parameter. The MRV parameter is presented as a discussion of the calculation and supported by precision data from a COULTER GEN-S System analyzer. Unlike the Sysmex R-1000, R-3000 and RAM-1 analyzers which are dedicated to the measurement of reticulocyte parameters, the COULTER hematology analyzers, including the GEN.S, measure multiple CBC and differential parameters in addition to the measurement of reticulocyte parameters.

No
The document mentions a "VCS Technology algorithm" for calculating MRV, but there is no mention of AI, ML, or related terms, nor is there any description of training or test sets which are typical for AI/ML models. The focus is on demonstrating substantial equivalence to predicate devices using traditional statistical methods.

No.
The device is an in vitro diagnostic (IVD) hematology analyzer used to quantify and classify blood components, which provides diagnostic information rather than treating or preventing disease.

Yes
The "Intended Use / Indications for Use" section explicitly states that it is "For In Vitro Diagnostic Use in clinical laboratories," and later describes it as a "device used to identify and classify one or more of the formed elements of blood," which are characteristics of a diagnostic device.

No

The device is described as a quantitative, automated hematology analyzer, which is a hardware system that performs laboratory tests on blood samples. While it utilizes software for analysis (VCS Technology algorithm), it is fundamentally a hardware device with integrated software, not a software-only device.

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

The "Intended Use / Indications for Use" section explicitly states: "For In Vitro Diagnostic Use in clinical laboratories."

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

The data in the Premarket Notification on safety and effectiveness supports a finding of substantial equivalence to hematology analyzers already in commercial distribution. Equivalence is demonstrated through compared sample accuracy and imprecision experiments.

§ 864.5220 Automated differential cell counter.

(a)
Identification. An automated differential cell counter is a device used to identify one or more of the formed elements of the blood. The device may also have the capability to flag, count, or classify immature or abnormal hematopoietic cells of the blood, bone marrow, or other body fluids. These devices may combine an electronic particle counting method, optical method, or a flow cytometric method utilizing monoclonal CD (cluster designation) markers. The device includes accessory CD markers.(b)
Classification. Class II (special controls). The special control for this device is the FDA document entitled “Class II Special Controls Guidance Document: Premarket Notifications for Automated Differential Cell Counters for Immature or Abnormal Blood Cells; Final Guidance for Industry and FDA.”

Dear Dr. Sugrue:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we 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). 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 (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
