Intended Use

Cal-Chex CD Plus is used to calibrate the WBC, RBC, Hgb, MCV, PLT and MPV (MPV on CD4000 only) parameters on the Abbott Cell-Dyn 3200 and 4000 hematology instruments.

Device Story

Cal-Chex CD Plus is a stabilized suspension of human red blood cells, white blood cells, and platelets in 3.0 mL glass vials. It serves as a calibrator for Abbott Cell-Dyn 3200 and 4000 hematology analyzers. The device is used by laboratory personnel to calibrate instrument parameters (WBC, RBC, Hgb, MCV, PLT, MPV). It utilizes a formulation optimized for systems employing Multiple Angle Polarized Scatter Separation (MAPSS) technology. By providing a stable, reproducible reference material, it ensures the accuracy of hematology instrument measurements, facilitating reliable clinical diagnostic results for patients.

Clinical Evidence

Bench testing only. Three studies were conducted: run-to-run reproducibility, comparison to whole blood calibration, and long-term/open-vial stability. Results confirmed consistent reproducibility and stability for the entire product dating, supporting equivalence to whole blood calibration.

Technological Characteristics

Suspension of stabilized human red blood cells, white blood cells, and platelets. Packaging: 3.0 mL glass vials with injection-molded polypropylene screw-top caps in PVC clamshells. Principle: Calibration reference material for hematology analyzers. Optimized for MAPSS (Multiple Angle Polarized Scatter Separation) technology.

Indications for Use

Indicated for the calibration of WBC, RBC, Hgb, MCV, PLT, and MPV parameters on Abbott Cell-Dyn 3200 and 4000 hematology instruments in a clinical laboratory setting.

Regulatory Classification

Identification

A calibrator for cell indices is a device that approximates whole blood or certain blood cells and that is used to set an instrument intended to measure mean cell volume (MCV), mean corpuscular hemoglobin (MCH), and mean corpuscular hemoglobin concentration (MCHC), or other cell indices. It is a suspension of particles or cells whose size, shape, concentration, and other characteristics have been precisely and accurately determined.

Special Controls

*Classification.* Class II (special controls). The device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 864.9.

Names of Device:

Cal-Chex CD Plus Trade Name: Assaved hematology calibrator Common Name: Calibrator for hemoglobin or hematocrit measurement (§864.8165) Classification Names: Calibrator for platelet counting (§864.8175) Hematology quality control mixture (§864.8625) 81KRZ, 81KRY and 81GLQ Classification Numbers:

Cal-Chex manufactured by Streck Laboratories, Inc. Predicate Devices:

Description: Cal-Chex CD Plus is a suspension of stabilized human red blood cells, human white blood cells, and human platelets packaged in glass vials containing 3.0 mL volumes. Closures are injection molded polypropylene screw-top caps. The vials are packaged in a PVC clamshell.

- Intended Use: Cal-Chex CD Plus is intended to be used as a calibrator for the calibration of WBC, RBC, Hgb, MCV, PLT and MPV (MPV on CD4000 only) on the Abbott Cell-Dyn 3200 and 4000 hematology instruments.
- Comparison with Predicate Devices: Like Cal-Chex CD Plus is a product utilized to calibrate hematology instrumentation for specified parameters.

Unlike Cal-Chex, Cal-Chex CD Plus utilizes a formulation that has been optimized for use as a calibrator on Abbott Cel-Dyn® Systems employing Multiple Angle Polarized Scatter Separation (MAPSS™) technology.

Discussion of Tests: Three studies of Cal-Chex CD Plus were conducted:

- I. Run-to-Run Reproducibility and Comparison to Whole Blood
- II. Long Term and Open Vial Stabilities;
- III. Verification as a calibrator. Study results showed Cal-Chex CD Plus to be consistently reproducible, substantially equivalent to whole blood calibration methods and stable for the entire product dating.
- Study results show Cal-Chex CD Plus to be Conclusions Drawn From Tests: consistently reproducible and stable for the entire product dating. Cal-Chex CD Plus is a safe and effective alternative to Whole Blood Calibration when utilized as instructed in the product package insert.
