N High Sensitivity CRP Assay
Not Found
No
The summary describes calibrators for a laboratory assay, which are standard reagents used to ensure the accuracy of the test. There is no mention of AI, ML, image processing, or any computational analysis beyond standard assay result interpretation.
No
The device is a calibrator for an assay kit, used for quantitative measurement of CRP, which is a diagnostic function, not a therapeutic one.
No
This device is a calibrator for an assay kit, meaning it is used to ensure the accuracy of a diagnostic test rather than performing the diagnosis itself. The diagnostic test (CRP-Latex (II)X2 SEIKEN Assay kit) quantitates CRP from human samples, which can be used for diagnosis, but the calibrator itself does not diagnose.
No
The device is described as a "Calibrator" for an assay kit, which implies a physical component used in a laboratory setting, not a software-only device.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use explicitly states that the calibrators are used for the "quantitating CRP (C-reactive protein) in human serum and EDTA or lithium heparinized plasma samples." This involves testing biological samples outside of the body to obtain diagnostic information.
- Device Description: The device is described as a "Calibrator" for an "Assay kit." Calibrators are essential components of many in vitro diagnostic tests, used to ensure the accuracy of the measurements.
- Performance Studies: The document mentions performance studies comparing the device to a "predicate device," which is common practice for demonstrating the equivalence of new IVDs to existing ones.
- Key Metrics: The mention of "lower level of detection (sensitivity of the assay)" and "assay range" are typical performance characteristics reported for IVD tests.
The fact that it is used to calibrate an assay kit for measuring a specific analyte (CRP) in human biological samples clearly places it within the definition of an In Vitro Diagnostic device.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The CRP-Latex (II) "Seiken"X2 High Sensitivity Assay and the predicate device, N High Sensitivity CRP Assay have only minor difference that do not affect the performance, safety or effectiveness of the measurement.
Key Metrics (Sensitivity, Specificity, PPV, NPV, etc.)
The lower level of detection (sensitivity of the assay) is at 0.05mg/L, with the assay range up to 10.0 mg/L.

Dear Mr. Matsunaga:
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.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in Title 21, Code of Federal Regulations (CFR), Parts 800 to 895. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Parts 801 and 809); and good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820). This letter will allow you to begin marketing your device as described in.your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
