Device Facts

• Record ID: K994388
• Device Name: XE CHECK
• Applicant: Streck Laboratories, Inc.
• Product Code: GLQ · Hematology
• Decision Date: Jan 14, 2000
• Decision: SESE
• Submission Type: Traditional
• Regulation: 21 CFR 864.8625
• Device Class: Class 2

Intended Use

XE Check is intended to be used as a control for evaluating complete blood cell count (CBC), white cell five-part differential, and reticulocyte percentage on Sysmex XE – 2100 series hematology instruments. The device will consist of three levels: Abnormal Low (characterized by low CBC, high reticulocyte %), Normal (normal CBC, normal reticulocyte %), and Abnormal High (high CBC, low reticulocyte %).

Device Story

XE Check is an assayed hematology control consisting of stabilized human red blood cells, human white cells, simulated human platelets, and simulated human reticulocytes. It is packaged in 4.6 mL glass vials with polypropylene caps. The device is used in clinical laboratory settings to verify the performance of Sysmex XE-2100 hematology instruments. Laboratory personnel process the control through the instrument to recover CBC, white cell differential, and reticulocyte parameters. By comparing instrument results against established control values, clinicians ensure the accuracy and reliability of patient sample analysis. This verification process supports clinical decision-making by ensuring the hematology analyzer is functioning correctly, thereby reducing the risk of erroneous patient test results.

Clinical Evidence

Bench testing only. Studies included lot-to-lot reproducibility, comparison to whole blood, long-term stability, and open-vial stability. Results confirmed consistent reproducibility and stability for the duration of product dating.

Technological Characteristics

Suspension of stabilized human red blood cells, human white cells, simulated human platelets, and simulated human reticulocytes. Packaged in 4.6 mL glass vials with injection-molded polypropylene screw-top caps. Standalone control material; no energy source or software.

Indications for Use

Indicated for use as a quality control material for complete blood cell count (CBC), white cell 5-part differential, and reticulocyte parameters on Sysmex XE-2100 hematology instruments. No specific patient population or contraindications described.

Regulatory Classification

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

• SF Check (Streck Laboratories, Inc.)
• Retic Chex (Streck Laboratories, Inc.)

Description: XE Check is a suspension of stabilized human red blood cells, human white cells.escription: XE Check is a suspension of stabilized human red blood cells, human white cells, simulated human platelets, and simulated human reticulocytes packaged in glass vials containing 4.6 mL volumes. Closures are injection molded polypropylene screw-top caps. The vials are packaged in polystyrene jars.

Intended Use: XE Check is intended to be used as a control for evaluating complete blood cell count (CBC), white cell five-part differential, and reticulocyte percentage on Sysmex XE – 2100 series hematology instruments. The device will consist of three levels: Abnormal Low (characterized by low CBC, high reticulocyte %), Normal (normal CBC, normal reticulocyte %), and Abnormal High (high CBC, low reticulocyte %).

Comparison with Predicate Devices: Like SF Check is intended to enable the user to verify satisfactory performance of Sysmex XE - 2100 instruments in recovery of CBC and white cell differential parameters on whole blood specimens. Both devices contain stabilized human red blood cells, human white cells, and simulated platelets which properly mimic human whole blood components on Sysmex XE - 2100.

Unlike SF Check, XE Check contains a stabilized human reticulocyte component, similar to Retic Chex. This allows the user to verify proper performance of the on-line reticulocyte analysis system in Sysmex XE -- 2100 instruments with the same device used for CBC and white cell differential analysis verification.

Discussion of Tests and Test Results: Three studies of XE Check were conducted: l) Lot to Lot Reproducibility and Comparison to Whole Blood; II) Long Term Stability; and III) Open Vial Stability. Study results showed XE Check to be consistently reproducible, substantially equivalent to the predicate products, and stable for the entire product dating.

Conclusions Drawn From Tests: XE Check is safe and effective for controlling CBC/Diff/Retic parameters on Sysmex XE - 2100 instruments when used as instructed in the product package insert.

## Dear Mr. Kittelson:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we 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). 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 (OS) 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.
