Intended Use
The PSA method for the Dimension® RxL with the heterogeneous immunoassay module is a device used to measure PSA in serum as an aid in the management of prostate cancer patients.
Device Description
The PSA method is a one-step enzyme immunoassay. Sample is incubated with chromium dioxide particles (CrO2) coated with monoclonal antibodies specific for a binding site on the PSA molecule and conjugate reagent [β-galactosidase (β-gal) labeled monoclonal antibodies specific for a second binding site on the PSA molecule] to form a particle/PSA/conjugate sandwich. Unbound conjugate and analyte are removed by magnetic separation and washing. The sandwich bound ß-gal catalyzes the hydrolysis of chlorophenol red-β-d galactopyranoside (CPRG) to chlorophenol red (CPR). The color change measured at 577nm due to the formation of CPR is directly proportional to the concentration of PSA present in the patient sample.

No
The device description details a standard enzyme immunoassay method for measuring PSA levels. There is no mention of AI, ML, or any computational analysis beyond the direct measurement of a color change proportional to PSA concentration. The performance studies focus on correlation with a predicate device, not on the performance of an AI/ML algorithm.

No
The device measures PSA in serum as an aid in the management of prostate cancer patients; it does not directly treat or provide therapy.

Yes

The device is used to measure PSA in serum to aid in the management of prostate cancer patients, which is a diagnostic purpose.

No

The device description clearly outlines a chemical assay involving reagents, particles, and a measurement of color change, indicating a hardware-dependent in vitro diagnostic device, not a software-only device.

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

Here's why:

  • Intended Use: The intended use explicitly states it's a "device used to measure PSA in serum". Measuring substances in bodily fluids (like serum) to aid in the management of a disease (prostate cancer) is a core function of IVDs.
  • Device Description: The description details a laboratory-based assay process involving chemical reactions and measurement of a color change. This is characteristic of in vitro diagnostic tests.
  • Input Imaging Modality: The "Not Applicable (In vitro diagnostic device)" entry further confirms its classification.
  • Anatomical Site: The "Not Applicable (In vitro diagnostic device)" entry also supports this.

The entire description points to a test performed on a sample taken from the body, outside of the body, to provide information about a patient's health status. This is the definition of an In Vitro Diagnostic device.

Summary of Performance Studies

Split sample comparison between the PSA method on the Dimension® RxL clinical chemistry system and the aca® plus PSA Test Kit gave a correlation coefficient of 0.994, slope of 1.06 ± 0.01 and an intercept of -0.07 ± 0.14 ng/mL when tested with 596 clinical patient samples ranging from 0,00 to 99.9 ng/mL. The Dimension® RxL assay compared well with the aca® plus assay in all healthy and disease state categories. Data obtained were consistent with the clinical status of the patient.

§ 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.
