Intended Use
The Chiron Diagnostics ACS:Centaur BR assay is an in vitro diagnostic test for the quantitative serial determination of cancer antigen CA 27.29 in human serum using the Chiron Diagnostics ACS:Centaur" Automated Chemiluminescence System. The test is intended for use as an aid in monitoring patients previously treated for Stage Il or Stage III breast cancer. Serial testing for CA 27,25 in the serum 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 breast cancer patients with metastatic disease by monitoring the progression or regression of disease in response to treatment.
Device Description
The Chiron Diagnostics ACS:Centaur BR assay is a fully automated, competitive immunoassay using direct, chemiluminescent technology. The Lite Reagent is composed of a monoclonal mouse antibody specific for CA 27.29, labeled with acridinium ester. The antibody used in the assay, MAb B27,29, binds to a peptide epitope in the tandem repeat region of the MUC-1 gene product. The Solid Phase is composed of purified CA 27.29, which is covalently coupled to paramagnetic particles. After onboard pretreatment, the sample is incubated with both Lite Reagent and Solid Phase simultaneously for 7.5 minutes.
More Information

No
The description focuses on a fully automated immunoassay using chemiluminescent technology and specific antibodies/reagents. There is no mention of AI, ML, or related concepts in the device description, intended use, or performance studies.

No
This device is an in vitro diagnostic test used to measure a cancer antigen in human serum, which aids in monitoring and managing breast cancer. It does not provide therapy.

Yes
The "Intended Use / Indications for Use" section explicitly states, "The Chiron Diagnostics ACS:Centaur BR assay is an in vitro diagnostic test..."

No

The device description clearly outlines physical components like reagents (Lite Reagent, Solid Phase) and paramagnetic particles, indicating it is a hardware-based in vitro diagnostic test, not software-only.

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

Here's why:

  • Intended Use/Indications for Use: The document explicitly states that the assay is an "in vitro diagnostic test" and describes its use for analyzing human serum to aid in monitoring and managing breast cancer patients. This directly aligns with the definition of an IVD, which is used to examine specimens taken from the human body to provide information for diagnosis, monitoring, or treatment.
  • Device Description: The description details a laboratory-based assay that uses chemical and biological components (antibodies, paramagnetic particles) to measure a specific analyte (CA 27.29) in a sample (human serum). This is characteristic of an in vitro diagnostic test.
  • Performance Studies: The document includes information about analytical performance characteristics like sensitivity and accuracy, which are standard evaluations for IVD devices.
  • Predicate Device: The mention of a predicate device (K981698; ACS:180 BR Immunoassay) indicates that this device is being compared to a previously cleared IVD, further confirming its classification.

§ 866.6010 Tumor-associated antigen immunological test system.

(a)
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.(b)
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.
