The CRP Vario assay is intended for the quantitative immunoturbidimetric determination of C-reactive protein in human serum or plasma. Cardiac CRP High Sensitive (cCRP) may be used for aid in identification of individuals at risk for cardiovascular disease. When used in conjunction with traditional clinical laboratory evaluation of acute coronary syndromes, the cCRP may be useful as an independent marker of prognosis for recurrents, in patients with stable coronary disease or acute coronary syndrome.

Device Description

Not Found

AI/ML Overview

The provided text is a 510(k) Premarket Notification clearance letter for a device called "CRP Vario." This document primarily
confirms the FDA's determination of substantial equivalence for a medical device to
a legally marketed predicate device.

Crucially, this document focuses on regulatory clearance and does NOT contain the detailed study information required to answer the
questions about acceptance criteria and device performance.

Specifically, the document states:

"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..."
The "Indications for Use" section describes what the device is intended for (quantitative immunoturbidimetric determination of C-reactive protein in human serum or plasma, and its use as an aid in identification of individuals at risk for cardiovascular disease).

To answer your questions about the acceptance criteria and the study that proves the device meets them, one would typically
need access to the underlying 510(k) submission document itself or efficacy study reports, which are not part of this
publicly available clearance letter.

Therefore, I cannot provide the requested information from the given text. The text does not contain:

A table of acceptance criteria and reported device performance.
Sample sizes used for test sets, data provenance, training set size, or how ground truth was established.
Details about expert involvement (number, qualifications, adjudication methods).
Information on MRMC comparative effectiveness studies or standalone algorithm performance.
The type of ground truth used.

Trade/Device Name: CRP Vario Regulation Number: 21 CFR 866.5270 Regulation Name: C-reactive protein immunological test system Regulatory Class: Class II Product Code: NQD Dated: September 21, 2018 Received: September 27, 2018

Dear Patricia Dupé:

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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. 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

{1}------------------------------------------------

requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801 and Part 809); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/CombinationProducts/GuidanceRegulatoryInformation/ucm597488.htm); good manufacturing practice requirements as set forth in the quality systems (OS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to http://www.fda.gov/MedicalDevices/Safety/ReportaProblem/default.htm.

For comprehensive regulatory information about medical devices and radiation-emitting products, including information about labeling regulations, please see Device Advice (https://www.fda.gov/MedicalDevices/DeviceRegulationandGuidance/) and CDRH Learn (http://www.fda.gov/Training/CDRHLearn). Additionally, you may contact the Division of Industry and Consumer Education (DICE) to ask a question about a specific regulatory topic. See the DICE website (http://www.fda.gov/DICE) for more information or contact DICE by email (DICE@fda.hhs.gov) or phone (1-800-638-2041 or 301-796-7100).
