CD-Chex PLUS control cells possess surface antigens detectable with monoclonal antibodies. When these cells are stained with fluorescent antibodies and analyzed by flow cytometry they provide a reference for normal peripheral blood leukocytes. CD-Chex PLUS is designed for use on Becton Dickinson and Coulter flow cytometry systems ## Device Story CD-Chex PLUS is an in vitro diagnostic control consisting of stabilized human red blood cells and human white blood cells in glass vials. It serves as a reference for normal peripheral blood leukocytes during flow cytometry analysis. The device is used by laboratory personnel to verify the performance of flow cytometry systems, specifically monoclonal antibody binding and the red cell lysing step. By providing a known reference, it allows clinicians to ensure the accuracy of immunophenotyping procedures. The control is stored at 2-10°C and is not intended for human use. ## Clinical Evidence Bench testing only. Four studies conducted: Lot-to-lot reproducibility and comparison to whole blood; site-to-site reproducibility and comparison to predicate device; long-term stability; and open-vial stability. Results demonstrated consistent reproducibility, stability for the entire product dating, and substantial equivalence to the predicate device. ## Technological Characteristics Suspension of stabilized human red and white blood cells. Packaged in 2.5 mL or 4.0 mL glass vials with polypropylene screw-top caps. Designed for use on Becton Dickinson and Coulter flow cytometry systems. Storage requirements: 2°C to 10°C; do not freeze. ## Regulatory Identification A hematology quality control mixture is a device used to ascertain the accuracy and precision of manual, semiautomated, and automated determinations of cell parameters such as white cell count (WBC), red cell count (RBC), platelet count (PLT), hemoglobin, hematocrit (HCT), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), and mean corpuscular hemoglobin concentration (MCHC). ## Special Controls *Classification.* Class II (special controls). Except when intended for use in blood components, 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. ## Predicate Devices - CD-Chex ([K920997](/device/K920997.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Closures are polypropylene screw-top caps. The vials are packaged in polystyrene jars. **Intended Use:** CD-Chex PLUS is intended to be used as a control for evaluating monoclonal antibody binding by flow cytometry. CD-Chex PLUS control cells possess surface antigens detectable with monoclonal antibodies. When these cells are stained with fluorescent antibodies and analyzed by flow cytometry they provide a reference for normal peripheral blood leukocytes. CD-Chex PLUS is designed for use on Becton Dickinson and Coulter flow cytometry systems **Comparison with Predicate Device:** Like CD-Chex, CD-Chex PLUS is intended to enable the user to verify satisfactory performance of flow cytometry systems. Both devices contain control cells which possess surface antigens detectable with monoclonal antibodies. Unlike CD-Chex, CD-Chex PLUS contains stabilized human red cells. This allows the user to verify proper performance of the red cell lysing step which gives the user a true positive procedural control. **Discussion of Tests and Test Results:** Four studies of CD-Chex PLUS were conducted: I) Lot to Lot Reproducibility and Comparison to Whole Blood; II) Site to Site Reproducibility and Comparison to Predicate Device; III) Long Term Stability; and IV) Open Vial Stability. Study results showed CD-Chex PLUS to be consistently reproducible, substantially equivalent to the predicate product, and stable for the entire product dating. **Conclusions Drawn from Tests:** CD-Chex PLUS is a safe and effective control for immunophenotyping when used as instructed in the product package insert. {1} Jar Label FRANÇAIS.
