Intended Use
ST AIA-PACK AFP is designed for IN VITRO DIAGNOSTIC USE ONLY for the quantitative measurement of Alpha-Fetoprotein (AFP) in serum to aid in the management of patients with nonseminomatous testicular carcinoma.
Device Description
The ST AIA-PACK AFP is a two-site immunoenzymometric assay which is performed entirely in the AIA-PACK. AFP present in the test sample is bound with monoclonal antibody immobilized on a magnetic solid phase and enzyme-labeled monoclonal antibody in the AIA-PACK. The magnetic beads are washed to remove unbound enzyme-labeled monoclonal antibody and are then incubated with a fluorogenic substrate, 4-methylumbelliferyl phosphate (4MUP). The amount of enzyme-labeled monoclonal antibody that binds to the beads is directly proportional to the AFP concentration in the test sample. A standard curve is constructed, and unknown sample concentrations are calculated using this curve.

No
The description details a standard immunoenzymometric assay with no mention of AI or ML algorithms for data analysis or interpretation. The calculation of unknown sample concentrations is based on a standard curve, a traditional method.

No.
The device is an in vitro diagnostic (IVD) tool used for quantitative measurement of Alpha-Fetoprotein (AFP) in serum, which aids in patient management but does not directly treat or prevent a disease.

Yes
The "Intended Use / Indications for Use" section explicitly states "IN VITRO DIAGNOSTIC USE ONLY for the quantitative measurement of Alpha-Fetoprotein (AFP) in serum to aid in the management of patients with nonseminomatous testicular carcinoma." This directly indicates its use for diagnostic purposes.

No

The device description clearly outlines a physical, in vitro diagnostic assay kit involving reagents, magnetic beads, and a fluorogenic substrate, indicating it is a hardware-based medical device, not software-only.

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

The "Intended Use / Indications for Use" section explicitly states:

"ST AIA-PACK AFP is designed for IN VITRO DIAGNOSTIC USE ONLY for the quantitative measurement of Alpha-Fetoprotein (AFP) in serum to aid in the management of patients with nonseminomatous testicular carcinoma."

This statement clearly indicates that the device is intended for use in vitro (outside of the body) to diagnose or aid in the diagnosis or management of a medical condition.

§ 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.

Device Description:

The ST AIA-PACK AFP is a two-site immunoenzymometric assay which is performed entirely in the AIA-PACK. AFP present in the test sample is bound with monoclonal antibody immobilized on a magnetic solid phase and enzyme-labeled monoclonal antibody in the AIA-PACK. The magnetic beads are washed to remove unbound enzyme-labeled monoclonal antibody and are then incubated with a fluorogenic substrate, 4-methylumbellifery| phosphate (4MUP). The amount of enzyme-labeled monoclonal antibody that binds to the beads is directly proportional to the AFP concentration in the test sample.

Statement of Intended Use:

ST AIA-PACK AFP is designed for IN VITRO DIAGNOSTIC USE ONLY for the quantitative measurement of Alpha-Fetoprotein (AFP) in human serum on specific TOSOH AIA System analyzers.

Substantial Equivalence:

This Special 510(k) is for a modification in the packaging, incubation period and certain components of the conjugate diluent of the AIA-PACK AFP, which was previously cleared as P910006 on December 18, 1992. The intended use, assay principles, antibody type, analyte detected, and performance characteristics of both assays are equivalent.

Conclusion:

The modified ST AIA-PACK AFP, as described in this Special 510(k) is substantially equivalent to the predicate device. The proposed modifications in packaging, incubation period and conjugate diluent are not substantial changes and do not affect the safety and effectiveness of the device.
