Company: 34 Bunsen Drive Irvine, CA 92618 Phone: (949) 453-0500 FAX: (949) 453-0600 Contact Person: Franck Brouzes Date Prepared: May 21, 1999 #### ABX™ PENTRA 120 RETIC Automated Hematology Trade Name: Analyzer | Common Name: | Automated cell counter and<br>Automated differential cell counter | |----------------------|-----------------------------------------------------------------------------------------| | Classification Name: | Automated cell counter (864.5200) and<br>Automated differential cell counter (864.5220) | #### 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 instrument is microprocessor driven. {1}------------------------------------------------ Image /page/1/Picture/3 description: The image is a logo for ABX Diagnostics. The logo is a stylized "ABX" in a bold, sans-serif font, with the letters stacked vertically. 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. 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. {2}------------------------------------------------ Image /page/2/Picture/3 description: The image is a logo for ABX Diagnostics. The logo is a black square with the letters "ABX" in white. The letters are stylized and overlapping. The word "DIAGNOSTICS" is printed in small letters below the square. Conclusions: All studies confirmed that the IRF clinical parameter of the ABX PENTRA 120 RETIC Automated Hematology Analyzer de substantially equivalent to the Sysmex IRF clinical parameter.

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. {4}------------------------------------------------ Page 2 Under the Clinical Laboratory Improvement Amendments of 1988 (CLIA-88), this device may require a CLIA complexity categorization.
