Intended Use
For in vitro diagnostic use in the quantitative, serial determination of CA 125 in human serum and plasma (EDTA and lithium heparin) and to aid in the management of patients with ovarian carcinoma using the ADVIA Centaur® XP and ADVIA Centaur® XPT systems. The test is intended for use as an aid in monitoring patients previously treated for ovarian cancer. Serial testing for CA 125 in the serum and plasma of patients who are clinically free of disease should be used in conjunction with other clinical methods used for the early detection of cancer recurrence. The test is also intended for use as an aid in the management of ovarian cancer patients with metastatic disease by monitoring the progression or regression of disease in response to treatment. It is recommended that the ADVIA Centaur CA 125II assay be used under the order of a physician trained in the management of gynecological cancers. This assay is not intended for screening or diagnosis of ovarian cancer or for use on any other system.
Device Description
The ADVIA Centaur CA 125II assay is comprised of the following reagents: CA 125II Lite Reagent (monoclonal mouse anti-M11 antibody labeled with acridinium ester and monoclonal mouse anti-OC 125 labeled with fluorescein in phosphate buffer with bovine serum albumin and preservatives) and CA 125II Solid Phase Reagent (monoclonal mouse anti-fluorescein antibody coupled to paramagnetic particles in phosphate buffer with bovine serum albumin and preservatives).

No
The summary describes a standard in vitro diagnostic assay for measuring CA 125 levels using immunoassay technology. There is no mention of AI, ML, image processing, or any other technology typically associated with AI/ML applications in medical devices. The performance studies focus on analytical metrics of the assay itself.

No.
The device is an in vitro diagnostic (IVD) test for quantitative determination of CA 125, used as an aid in the management and monitoring of ovarian cancer, not for direct treatment or therapy.

Yes

The 'Intended Use / Indications for Use' section explicitly states that the device is "For in vitro diagnostic use." It also describes its use in the "quantitative, serial determination of CA 125 in human serum and plasma" to "aid in the management of patients with ovarian carcinoma" and for "monitoring patients previously treated for ovarian cancer" and "monitoring the progression or regression of disease." These are all diagnostic applications.

No

The device description explicitly states it is comprised of "reagents," which are physical components, not software. The device is an in vitro diagnostic assay, which is a chemical test performed on biological samples.

Yes, this device is an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The "Intended Use / Indications for Use" section explicitly states "For in vitro diagnostic use".
  • Nature of the Test: The device performs a "quantitative, serial determination of CA 125 in human serum and plasma". This is a laboratory test performed on biological samples outside of the body, which is the definition of an in vitro diagnostic.
  • Device Description: The description details reagents used to perform a chemical reaction on the sample, further confirming its in vitro nature.

N. Test Principle

The ADVIA Centaur CA 125II assay is a two-site sandwich immunoassay using direct chemiluminometric technology, which uses two monoclonal mouse antibodies specific for CA 125. The first antibody is directed toward the M11 antigenic domain, and is labeled with acridinium ester. The second antibody is directed toward the OC 125 antigenic domain and is labeled with fluorescein. The immunocomplex formed with CA 125 is captured with monoclonal mouse anti-fluorescein antibody coupled to paramagnetic particles in the Solid Phase.

A direct relationship exists between the amount of CA 125 present in the patient sample and the amount of relative light units (RLUs) detected by the system.

O. Performance Characteristics

The assay principle, design and reagent formulation has not changed from the original device, therefore, the analytical performance studies and data previously reviewed under 510(K) K020828 continues to apply to this assay.

Detection Limit .

Detection capability was determined in accordance with CLSI Document EP17-A2.

Limit of Blank (LoB)2.0 U/mL
Limit of Detection (LoD)3.0 U/mL
Limit of Quantitation (LoQ)3.0 U/mL

The LoB corresponds to the highest measurement result that is likely to be observed for a blank sample with a probability of 95%.

The LoD corresponds to the lowest concentration of CA 125 that can be detected with a probability of 95%.

Image /page/7/Picture/0 description: The image shows the logo for Siemens Healthineers. The word "SIEMENS" is in teal, and the word "Healthineers" is in orange. To the right of the words is a graphic of orange dots arranged in a circular pattern.

The LoQ corresponds to the lowest amount of CA 125 in a sample at which the within-laboratory CV is ≤ 20%.

II. Method Comparison

For 224 samples in the range of 3.1 to 466.6 U/mL, the relationship of the ADV/A Centaur CA 125Il assay to the Bayer Immuno 1® CA 125II assay is described by the following equation:

ADVIA Centaur CA 125II = 1.025 (Bayer Immuno 1) + 1.15 U/mL

Correlation coefficient (r) = 0.992

Specimen Equivalence lll.

The study was performed in accordance with CLSI Document EP09-A3 to demonstrate that EDTA and Li-heparin plasma matrices yield comparable results as serum with the ADVIA Centaur CA 125 II assay. A Deming linear regression analysis was performed, and the corresponding slopes of regression and coefficient determination are summarized in the following table:
