The description details a standard automated chemiluminescent immunoassay system and its components, with no mention of AI or ML algorithms for data analysis, interpretation, or system control.
No
The device is an in vitro diagnostic test used to measure a cancer antigen in human serum to aid in monitoring breast cancer patients, not to treat them.
Yes
Explanation: The "Intended Use / Indications for Use" section explicitly states that the device is "an in vitro diagnostic test for the quantitative serial determination of cancer antigen CA 27.29 in human serum" and is "intended for use as an aid in monitoring patients previously treated for Stage II or Stage III breast cancer" and "as an aid in the management of breast cancer patients with metastatic disease." This directly aligns with the definition of a diagnostic device.
No
The device description clearly outlines a fully automated, competitive, chemiluminescent assay system involving physical reagents (Lite Reagent, Solid Phase), paramagnetic particles, and automated steps like dispensing, incubation, separation, aspiration, washing, and detection of relative light units. This indicates a hardware-based in vitro diagnostic system, not a software-only device.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The "Intended Use / Indications for Use" section explicitly states that the device is an "in vitro diagnostic test" for the quantitative determination of cancer antigen CA 27.29 in human serum.
- Sample Type: The test is performed on "human serum," which is a biological sample taken from the body.
- Purpose: The test is used to aid in monitoring patients previously treated for breast cancer and to aid in the management of breast cancer patients with metastatic disease by monitoring disease progression or regression. These are diagnostic purposes performed outside of the living body.
- Device Description: The description details a "fully automated, competitive, chemiluminescent assay," which is a common type of in vitro diagnostic test.
All of these points align with the definition of an In Vitro Diagnostic device.

Intended Use / Indications for Use
The Chiron Diagnostics ACS:180 BR 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:180® Automated Chemiluminescence Systems. The test is intended for use as an aid in monitoring patients previously treated for Stage II or Stage III breast cancer. Serial testing for CA 27.29 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:180 BR assay is a fully automated, competitive, chemiluminescent assay. One reagent, designated Lite Reagent, is composed of a mouse monoclonal 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 breast cancer antigen (CA 27.29) which is covalently coupled to paramagnetic particles (PMP). After onboard pretreatment, the patient serum sample is incubated with both reagents simultaneously for 7.5 minutes.
The ACS: 180 system automatically performs the following steps:
- dispenses sample and Pretreatment Reagent into a cuvette .
- dispenses Lite Reagent and Solid Phase and incubates for 7.5 minutes u
- separates, aspirates and washes the cuvettes
- dispenses reagents which initiate the chemiluminescent reaction
- = reports results
An inverse relationship exists between the concentration of CA27.29 in a sample and the relative light units (RLU) detected by the system.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The performance of the modified ACS:180 BR assay was compared to that of the predicate device in studies of over 875 specimens from breast cancer patients. These specimens had CA 27.29 levels that spanned the range from 3.68 U/mL to 420 U/mL. The results of the linear regression analysis indicated that the two methods were correlated. The coefficient of determination (r2) was greater than 0.99, the slope was 1.0408 and the y-intercept was 0.9907 U/mL.

(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.

Dear Ms. Hornbaker:
We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to 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). 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 (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (QS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in requlatory action. In addition, FDA may publish further announcements concerning your device in the Federal Reqister. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal Laws or Regulations.
