Intended Use

XN CAL is used for the calibration and calibration verification of Sysmex XN series (XN-10, XN-11, XN-20, XN-21) analyzers. Assayed parameters include: WBC (10³/μL), RBC (10⁶/μL), HGB (g/dL), HCT (%), PLT (10³/μL), and RET (%).

Device Story

XN CAL is an in-vitro diagnostic calibrator designed to substitute for fresh whole blood in Sysmex XN series hematology analyzers. It consists of stabilized red blood cells, white blood cells, platelets, and nucleated red blood cells in a preservative medium. Packaged in polypropylene vials, it is used by laboratory personnel to calibrate and verify the accuracy of WBC, RBC, HGB, HCT, PLT, and RET parameters. The device ensures analyzer performance remains within specified limits, supporting accurate clinical hematology testing. It is stored at 2-8°C and has a 49-day closed-vial stability.

Clinical Evidence

Bench testing only. Studies included open-vial stability (4 hours), closed-vial stability (49 days), and precision performance. Data demonstrated consistent reproducibility and stability for the entire product dating, supporting substantial equivalence.

Technological Characteristics

Stabilized human blood components (RBC, WBC, PLT, nucleated RBC) in preservative medium. Polypropylene vials with screw caps. Calibrated to whole blood per CLSI H26-A2, H7-A3, H15-A3, and ICSH guidelines. Storage 2-8°C. No electronic or software components; purely a chemical/biological calibrator.

Indications for Use

Indicated for calibration and calibration verification of Sysmex XN series (XN-10, XN-11, XN-20, XN-21) hematology analyzers. Used by clinical laboratory professionals.

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.

Dear Ms. Kipp:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food. Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls.
