Intended Use
The DSL-9700 Active™ PSA Immunoradiometric Assay (IRMA) Kit provides materials for the quantitative measurement of Total PSA in human serum to aid in the management (monitoring the reoccurrence of prostate cancer) of prostate cancer patients. This assay is intended for in vitro diagnostic use.
Device Description
The IRMA format is a non-competitive assay in which the analyte to be measured is "sandwiched" between two antibodies. The first antibody is immobilized to the coated tube, the other antibody is radiolabelled for detection. The analyte present is bound by both the antibodies to form a "sandwich" complex. Unbound materials are removed by decanting and washing the tube. The resultant is analyzed in a gamma counter for net counts. The amount of bound PSA is directly proportional to the concentration of the PSA present in the sample.

No
The device description details a standard immunoradiometric assay (IRMA) which is a biochemical method for measuring analyte concentration. There is no mention of AI or ML in the device description, intended use, or performance studies. The performance studies focus on correlation with a predicate device, not on training or testing AI/ML models.

No
This device is an in vitro diagnostic assay used for quantitative measurement of Total PSA in human serum to aid in the management of prostate cancer patients, not for direct therapeutic intervention.

Yes

The Intended Use section explicitly states that the assay is "intended for in vitro diagnostic use."

No

The device is an in vitro diagnostic (IVD) kit that uses chemical reagents and a gamma counter (hardware) to measure PSA levels. It is not a software-only device.

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

Here's why:

  • Explicit Statement: The "Intended Use / Indications for Use" section clearly states: "This assay is intended for in vitro diagnostic use."
  • Nature of the Assay: The device description details an "Immunoradiometric Assay (IRMA) Kit" that measures "Total PSA in human serum." This is a laboratory test performed on biological samples (serum) outside of the body, which is the definition of an in vitro diagnostic.
  • Intended Use: The intended use is "to aid in the management (monitoring the reoccurrence of prostate cancer) of prostate cancer patients." This is a diagnostic purpose, providing information to healthcare professionals for patient management.
  • Intended User / Care Setting: The "in vitro diagnostic use" further reinforces that it's used in a laboratory or clinical setting for diagnostic purposes.

All these points align with the definition and characteristics of an In Vitro Diagnostic device.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

To demonstrate substantial equivalence between the two assays, human serum samples (n = 286) were collected and assayed using both methods. Samples were chosen based on expected PSA levels so that samples with low, intermediate and high levels would be evaluated. Linear regression analysis of the results obtained for the comparison gave the equation Y = 1.25(DPC IMMULITE) + 0.33 with a correlation coefficient of (r) = 0.97.

Key Metrics (Sensitivity, Specificity, PPV, NPV, etc.)

§ 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.

The first antibody is immobilized to the coated tube, the other antibody is radiolabelled for detection. The analyte present is bound by both the antibodies to form a "sandwich" complex. Unbound materials are removed by decanting and washing the tube. The resultant is analyzed in a gamma counter for net counts. The amount of bound PSA is directly proportional to the concentration of the PSA present in the sample.

The DSL PSA IRMA assay is intended for the quantitative determination of PSA in human serum to aid in the management (monitoring the reoccurrence of prostate cancer) of prostate cancer patients.

The DSL 9700 PSA IRMA is substantially equivalent to the DPC IMMULITE PSA assay.

To demonstrate substantial equivalence between the two assays, human serum samples (n = 286) were collected and assayed using both methods. Samples were chosen based on expected PSA levels so that samples with low, intermediate and high levels would be evaluated. Linear regression analysis of the results obtained for the comparison gave the equation Y = 1.25(DPC IMMULITE) + 0.33 with a correlation coefficient of (r) = 0.97.
