The Vitros CA 125 II assay is to be used as an aid in monitoring response to therapy for patients with epithelial ovarian cancer. Serial testing for patient CA 125 assay values should be used in conjuction with other clinical methods used for monitoring ovarian cancer. ## Device Story VITROS CA 125 II assay is an in vitro diagnostic test for quantitative measurement of OC 125 antigen in human serum or plasma. System utilizes luminescence-based immunoassay technology with coated microwells as solid phase separation. Operated on VITROS Immunodiagnostic System instrumentation; system automates immunoassay process. Healthcare providers use serial test results in conjunction with other clinical methods to monitor therapeutic response in ovarian cancer patients. Device provides quantitative output to assist clinical decision-making regarding patient management. ## Clinical Evidence Clinical performance evaluated via comparison with predicate device using samples from various clinical categories. Bablock Passing regression analysis yielded a correlation coefficient of 0.946. Analytical studies performed include analytical sensitivity, specificity, precision, and dilution testing. ## Technological Characteristics Luminescence-based immunoassay; solid phase separation using coated microwells. Requires VITROS Immunodiagnostic System instrumentation. Compatible with serum, EDTA plasma, or heparin plasma. Automated system. ## Regulatory Identification A tumor-associated antigen immunological test system is a device that consists of reagents used to qualitatively or quantitatively measure, by immunochemical techniques, tumor-associated antigens in serum, plasma, urine, or other body fluids. This device is intended as an aid in monitoring patients for disease progress or response to therapy or for the detection of recurrent or residual disease. ## Special Controls *Classification.* Class II (special controls). Tumor markers must comply with the following special controls: (1) A guidance document entitled “Guidance Document for the Submission of Tumor Associated Antigen Premarket Notifications (510(k)s) to FDA,” and (2) voluntary assay performance standards issued by the National Committee on Clinical Laboratory Standards. ## Predicate Devices - Boehringer Mannheim Elecsys CA 125 II ([K972162](/device/K972162.md)) ## Reference Devices - VITROS Immunodiagnostic System ([K962919](/device/K962919.md)) - VITROS Immunodiagnostic Products Total T3 ([K964310](/device/K964310.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Device Name Trade or Proprietary Name: VITROS Immunodiagnostic Products CA 125 II Calibrators VITROS Immunodiagnostic Products CA 125 II Reagent Pack Common Name: CA 125 II assay Classification Name: test for the in vitro quantitative determination of OC 125 defined antigen in serum or plasma. ## 3. Predicate Device The VITROS Immunodiagnostic Products CA 125 II assay is substantially equivalent to the Boehringer Mannheim Elecsys CA 125 II (K972162). ## 4. Device Description The VITROS Immunodiagnostic System uses luminescence as the signal in the quantitative and semi-quantitative determination of selected analytes in human body fluids, commonly serum and plasma. Coated microwells are used as the solid phase separation system. The system is comprised of three main elements: - 1. The VITROS Immunodiagnostic Products (in this casc VITROS Immunodiagnostic Products CA 125 II Reagent Pack, VITROS Immunodiagnostic Products CA 125 II Calibrators, which are combined by the VITKOS Immunodiagnostic System to perform the VITROS CA 125 Il assay). {1}------------------------------------------------ ## VITROS CA 125 II assay - 2. The VITROS Immunodiagnostic System instrumentation, which provides automated use of the immunoassay kits. The VITROS Immunodiagnostic System was cleared for market by a separate 510(k) pre-market notification (K962919). - 3. Common reagents used by the VITROS System in each assay. The VITROS Immunodiagnostic Products Signal Reagent and VITROS Immunodiagnostic Products Universal Wash Reagent were cleared as part of the VITROS Immunodiagnostic Products Total T3 510(k) pre-market notification (K964310). The VITROS System and common reagents are dedicated specifically only for use with the VITROS Immunodiagnostic Products range of immunoassay products. ## 5. Device Intended Use The Vitros® CA 125 II is an in vitro assay intended for the quantitative measurement of OC 125 defined antigen in the serum or plasma (EDTA or heparin). The Vitros CA 125 II assay is to be used as an aid in monitoring response to therapy for patients with epithelial overian cancer. Serial testing for patient CA 125 assay values should be used in conjuction with other clinical methods used for monitoring ovarian cancer. #### 6. Comparison to Predicate Device The VITROS Immunodiagnostic Products CA 125 II assay is substantially equivalent to Boehringer Mannheim Elecsys CA 125 II (predicate device), which was cleared by FDA (K972162) for IVD use. The relationship between the VITROS CA 125 II assay and the predicate device, determined by Bablock Passing regression, is VITROS CA 125 II assay = 0.963 x [Boehringer Mannheim Elecsys CA 125 II] + 0.654 (U/mL), with a correlation coefficient of 0.946. Comparisons of the VITROS CA 125 II assay and the predicate device were performed with samples from a variety of clinical categories. In addition to the studies mentioned above, tests were performed to obtain analytical sensitivity, specificity, precision, dilution and expected values. Refer to the VITROS CA 125 II assay package insert for VITROS CA 125 11 assay results. Table 1 lists the similarities and differences of the device characteristics between the VITROS CA 125 II assay with the predicate device: {2}------------------------------------------------ DEPARTMENT OF HEALTH & HUMAN SERVICES Image /page/2/Picture/1 description: The image is a black and white logo for the U.S. Department of Health & Human Services.
