The description mentions "automated cell population cluster analysis is performed by the software," which is a standard data analysis technique and does not inherently indicate the use of AI or ML. There are no explicit mentions of AI, ML, or related terms like neural networks or deep learning.
No.
The FlowCare System is an in vitro diagnostic (IVD) device used to enumerate white blood cell populations and T-lymphocyte subsets from human whole blood, providing diagnostic information rather than directly treating or preventing disease.
Yes
The "Intended Use / Indications for Use" section explicitly states that the FlowCare System is "intended for in vitro diagnostic use." It performs "direct enumeration of White Blood Cell populations and certain T-lymphocyte subsets from human whole blood," which are diagnostic measurements.
No
The device description explicitly states that the FlowCare System is comprised of an analysis instrument, a touch screen computer, and a standard inkjet printer, in addition to the software. It also mentions automated aspiration, dispensing, and mixing steps, indicating hardware components are involved.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Explicit Statement: The "Intended Use / Indications for Use" section clearly states: "The FlowCare System is an automated immune hematology system intended for in vitro diagnostic use..." and "...intended for in vitro diagnostic use in clinical laboratory settings."
- Nature of the Test: The device analyzes human whole blood samples to enumerate specific cell populations (WBCs, Lymphocytes, CD4 T-Lymphocytes). This type of analysis performed on biological samples outside of the body is the definition of an in vitro diagnostic test.
- Clinical Laboratory Setting: The intended use specifies that the device is for use in "clinical laboratory settings," which is a typical environment for IVD devices.
Therefore, based on the provided information, the FlowCare System is definitively an In Vitro Diagnostic device.

Device Description
The FlowCare System is a compact benchtop immune hematology system that reports CD4 T-Lymphocyte count and percentage in conjunction with White Blood Cell (WBC) count, and total Lymphocyte count and percentage from analysis of a whole blood sample. The FlowCare System is comprised of an analysis instrument, a touch screen computer and a standard inkjet printer. The FlowCare CD4 Reagent Kit is used in conjunction with the FlowCare System.
All assay steps are performed on whole blood with capped bar-coded reagent tubes designed for use on the FlowCare System. All assay aspiration, dispensing and mixing steps are automated. The FlowCare System reports parameter results on the basis of software analysis of light scatter measurements with the use of nonfluorescent reagents. Automated cell population cluster analysis is performed by the software and results provided with no operator interpretation.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Electrical Testing: The FlowCare Instrument underwent electrical safety testing and electromagnetic compatibility testing. The instrument was found to be in compliance with applicable requirements of UL 61010A-1, CSA C22.2 1010-1, EN 61326-1 and EN 55011 (CISPR 11).
Nonclinical Testing:
A precision study was performed to assess the within-run and total precision of the FlowCare System by replicate measurements of control materials for three days. On cach day, testing consisted of three separate runs of three replicates each with each level of control material. In addition, another precision study was performed to assess within-day precision using whole blood samples. The samples were analyzed in three separate runs of three replicates each over the course of one day. Results of these studies demonstrated acceptable precision of the FlowCare System.
A linearity study was performed to assess the performance of the FlowCare System over a wide range of cell concentrations for the measured parameters. CD4 count was further evaluated in the low range. The results were tested for linearity and least squares regression analysis was performed. Linearity was demonstrated in all cases.
A carryover study was performed to assess the effect of a whole blood sample on background counts in subsequent analyses for the measured parameters. Negligible carryover was observed.
Clinical Testing:
A multi-site prospective study was conducted at four investigational sites to evaluate the performance of the FlowCare System with other commercially available methods. A total of 414 evaluable samples were analyzed across all participating sites. Data analyses were performed for comparison of the FlowCare method to the reference methods, and for the determination of an expected normal values reference range for the FlowCare method. The analyses of the pooled data showed comparable means and ranges for the FlowCare and reference method parameters.

(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.”

TECHNOLOGICAL CHARACTERISTICS AND SUBSTANTIAL EQUIVALENCE 6.
The FlowCare System reports CD4 T-Lymphocyte counts and percentage in conjunction with White Blood Cell (WBC) count and total Lymphocyte count information, on the basis of software analysis of light scatter measurements with the use of non-fluorescent reagents. The FlowCare System and predicate devices are all intended for the determination of well-established parameters. All of the devices utilize anticoagulated whole blood as the initial specimen. Additionally, all of the devices employ flow-based technologies. The primary difference between the FlowCare System and the predicate devices is that the FlowCare System includes a single compact instrument whereas the predicate hematology analyzer and flow
2
cytometer are larger, more complex systems that must be used in conjunction with each other to provide results for the five parameters included in this 510(k) Premarket Notification.

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 (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in Title 21, Code of Federal Regulations (CFR), Parts 800 to 895. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Parts 801 and 809); and good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820). This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
