Device Description
The product is an automated hematology analyzer capable of supplying a complete blood cell analysis and includes a differential leukocyte cell count. The product also provides automated reticulocyte analysis and enumeration of nucleated red blood cells (NRBCs). The following reagents, with 510(k) numbers indicated where applicable, are qualified for use on the COULTER LH 750 Hematology Analyzer with Version 2A software:
- · 5C® -ES Cell Control (K010066) and COULTER RETIC-C™ Cell control (K930119) hematology quality control materials used to monitor the instrument performance. COULTER® LIN-C® linearity control (K955334) verifies reportable range of the CBC parameters.
- · COULTER® LH 700 SERIES Diluent. Intended for use as a diluent for counting and sizing blood cells on COULTER® LH 700 SERIES hematology analyzers.
- · COULTER Lyse S® III diff. Intended for the simultaneous quantitative determination of hemoglobin and for leukocyte counting and sizing on COULTER® hematology analyzers.
- · COULTER CLENZ® cleaning agent to prevent protein buildup on surfaces.
- · COULTER Latron™ Primer and Latron Control (K885028) to monitor VCS performance.
- · COULTER LH 700 SERIES Pak, containing Erythrolyse™ lytic reagent and Stabilyse™ to preserve leukocytes in near-native state to allow differentiation into subpopulations.
- · COULTER LH 700 SERIES RETIC Pak, containing Reagent A and Reagent B, is used for clearing red cells and staining reticulocytes.
- · COULTER S-CAL® Hematology Calibrator (K840794). alternative to whole blood reference method of calibration. Intended for use in ensuring accurate instrument measurements.
The COULTER LH 750 Hematology Analyzer with Version 2A software has the same technological characteristics and is substantially equivalent to the COULTER LH 750 Hematology Analyzer with Version 1A software. Both devices utilize the Coulter Principle for enumerating and sizing blood cells, automatic diluting and mixing for sample processing and a single beam photometer for hemoglobinometry. They use COULTER VCS (volume. conductivity, light scatter) technology for WBC Differential analysis and classification and reticulocyte analysis. The analyzers use a reagent system consisting of an isotonic diluent. lytic reagents to lyse the red cells without significantly affecting the white cells and an instrument cleaner. Additionally, all systems include reagents used for reticulocyte staining and analysis.

§ 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.”
