The summary describes a standard automated hematology analyzer using established principles (cytochemistry, impedance, light scattering, fluorescence) and a microprocessor. There is no mention of AI, ML, or related terms, nor any description of algorithms that would typically involve these technologies. The "flags and alarms" are likely based on predefined thresholds, not learned patterns.
No
The device is an automated hematology analyzer used for in vitro diagnostic (IVD) purposes in clinical laboratories to provide complete blood counts, differential leucocyte counts, and reticulocyte counts. It is used for diagnosis and monitoring, not for treating or preventing disease.
Yes
This device is described as an "Automated Hematology Analyzer for in vitro diagnostic use in clinical laboratories," and it provides various blood counts (CBC, differential, reticulocyte) which are used for diagnosis. Additionally, it mentions that the clinical use of the reticulocyte count is to "monitor erythropoietic activity in patients," indicating its role in patient assessment and diagnosis.
No
The device description explicitly states it is a "benchtop, clinical laboratory instrument" that uses physical principles like cytochemistry, focused flow impedance, light scattering, and fluorescence to analyze samples. This indicates it is 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:
"The ABX PENTRA 120 RETIC Automated Hematology Analyzer is an automated hematology analyzer providing complete blood count (CBC), differential leucocyte count (DIFF) as well as reticulocyte count for in vitro diagnostic use in clinical laboratories."

Summary of Performance Studies
The determination of substantial equivalence was based on an assessment of clinical performance data from published studies and from a clinical study using whole blood samples from 100 patients with normal reticulocyte counts and 103 patients with abnormal counts. In the clinical study, samples were processed in the ABX PENTRA 120 RETIC Automated Hematology Analyzer and the SYSMEX R-3000 analyzer. Clinical data support substantial equivalence for the IRF parameter. Additional studies were conducted to assess the precision and accuracy of the ABX PENTRA 120 RETIC Automated Hematology Analyzer.

§ 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.”

Substantial Equivalence:
The ABX PENTRA 120 RETIC Automated Hematology Analyzer is substantially equivalent to the ABX PENTRA 120 RETIC Automated Hematology Analyzer (K990311, cleared to market March 31, 1999) and to the Sysmex™ IRF clinical parameter (K971736, cleared to market August 26, 1997).
Description:
The ABX PENTRA 120 RETIC Automated Hematology Analyzer is a benchtop, clinical laboratory instrument which analyzes in-vitro samples of whole blood to provide complete blood count, leucocyte differential count and reticulocyte count using principles of cytochemistry, focused flow impedance, light scattering, and fluorescence.

The "A" is at the top, the "B" is in the middle, and the "X" is at the bottom. The word "DIAGNOSTICS" is written in a smaller, sans-serif font below the letters. The logo is black and white.
Indications For Use:
The ABX PENTRA 120 RETIC Automated Hematology Analyzer is an automated hematology analyzer providing complete blood count, differential leucocyte count as well as reticulocyte count for in vitro diagnostic use in clinical laboratories. The ABX PENTRA 120 RETIC Automated Hematology Analyzer provides appropriate flags and alarms to assist users in final checking and identification of abnormal cell populations.
The clinical use of the reticulocyte count, specifically the immature reticulocyte fraction (IRF) is to monitor erythropoietic activity in patients.
Comparison to Predicate Devices:
ABX PENTRA 120 RETIC Automated Hematology Analyzer is identical to the ABX PENTRA 120 RETIC Hematology Analyzer with respect to the reagents and controls, measuring principles, principles of operation, hardware, and software. The ABX PENTRA 120 RETIC Automated Hematology Analyzer labeling was modified to include an additional parameter for reticulocyte counts: the IRF parameter. With respect to this parameter, the IRF parameter is substantially equivalent to the Sysmex R-Series IRF parameter. ABX Diagnostics defines the IRF parameter as the sum of the medium and high RNA content reticulocytes (as %). Sysmex Corporation defines the IRF parameter as the sum of the middle fluorescence ratio and the high fluorescence ratio.
Discussion of Performance Data:
The determination of substantial equivalence was based on an assessment of clinical performance data from published studies and from a clinical study using whole blood samples from 100 patients with normal reticulocyte counts and 103 patients with abnormal counts. In the clinical study, samples were processed in the ABX PENTRA 120 RETIC Automated Hematology Analyzer and the SYSMEX R-3000 analyzer.
