The summary describes a standard immunoassay system and does not mention any AI or ML components.
No
The device is an immunoassay system used for the quantitative determination of alpha-fetoprotein (AFP) in human serum, which aids in the management of patients with nonseminomatous testicular cancer. It is a diagnostic tool, not a therapeutic one.
Yes
The device is described as an "immunoassay for the quantitative determination of alpha-fetoprotein (AFP) in human serum" and is "used as an aid in the management of patients with nonseminomatous testicular cancer," which clearly indicates its role in diagnosing or managing a disease.
No
The device description explicitly states that the system comprises both "Immunoassay Reagents" and an "Immunoassay Analyzer," indicating the presence of hardware components in addition to any potential software.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use explicitly states it's for the "quantitative determination of alpha-fetoprotein (AFP) in human serum". This involves testing a biological sample (serum) outside of the body (in vitro).
- Device Description: The description mentions "Immunoassay Reagents" and an "Immunoassay Analyzer," which are components typically used in laboratory settings to perform tests on biological samples.
- Performance Studies: The performance studies describe analytical characteristics like correlation, expected range, monitoring data, recovery, precision, specificity, and analytical sensitivity. These are all metrics relevant to the performance of an in vitro diagnostic test.
- Predicate Device: The mention of a "Predicate Device" (Abbott IMx AFP Immunofluorometric Assay) which is also an immunoassay for AFP, further confirms that this device falls under the category of IVDs.
The core function of the device is to analyze a biological sample (serum) to measure a specific substance (AFP) for diagnostic purposes (aid in the management of patients with nonseminomatous testicular cancer). This aligns perfectly with the definition of an In Vitro Diagnostic device.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Correlation: A comparison of AFP values from 170 samples, ranging from 0,90 to 3000 ng/ml, run with both the ACCESS AFP Immunoassay and the Abbott IMx AFP assay demonstrated very good agreement with the following statistical data: r = 0.99; y = 0.91x + 3.86.
Expected Range: In a population of 177 apparently healthy males and females, 98.9% had AFP values of 9.0 ng/mL or less, with the remaining 1.1% having values in the 9.1 to 15 ng/mL range.
Monitoring Data: Longitudinal samples from previously diagnosed nonseminomatous testicular cancer patients were compared using the ACCESS AFP and Abbott IMx AFP assays. The monitoring patient data demonstrate that the ACCESS AFP results are highly concordant to both the IMX AFP results and the concurrent clinical assessment.
Recovery: Linearity studies performed by diluting human serum samples with ACCESS AFP Sample Diluent provided recoveries ranging from 96 to 110%. Recovery of exogenous AFP (from cord serum) spiked into serum samples resulted in an average recovery of 99%, with individual recoveries ranging from 90 to 108%.
Precision: The ACCESS AFP assay exhibits assay imprecision of less than 6% for AFP concentrations ranging from approximately 6.5 to 1680 ng/ml.
Specificity: There was no significant interference from potential biological substances. therapeutic drugs or other cross-reacting substances.
Analytical Sensitivity: The lowest detectable level of AFP distinguishable from zero (ACCESS AFP Calibrator S0) with 95% confidence is 0.5 ng/ml.

§ 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.

PMA Number: P820060
3. Device Description
The ACCESS® AFP Immunoassay Reagents and the ACCESS® Immunoassay Analyzer comprise the ACCESS® Immunoassay System for the quantitative determination of AFP in human serum.
4. Indications for Use
The ACCESS AFP Immunoassay is a paramagnetic particle chemiluminescent immunoassay for the quantitative determination of alpha-fetoprotein (AFP) in human serum using the ACCESS Immunoassay System. AFP, measured by the ACCESS AFP Immunoassay, is intended for use as an aid in the management of patients with nonseminomatous testicular cancer.
5. Comparison of Technological Characteristics
Both the ACCESS AFP Immunoassay and the Abbott IMx AFP assay quantitatively measure serum AFP by means of simultaneous immunoassays utilizing the binding of AFP to monoclonal antibodies specific to epitopes on the AFP molecule. Both systems utilize liquid multi-point calibrators.
The ACCESS AFP Immunoassay Reagents are designed for use on the ACCESS Immunoassay Analyzer, a fully automated random access system, while the Abbott IMx AFP assay is a batch mode system. The ACCESS Immunoassay Analyzer uses magnetic particle solid phase enzyme immunoassays with chemiluminescent detection, while the Abbott IMx AFP assay uses a glass fiber solid phase and fluorescent detection. The Access AFP assay can measure samples with AFP concentrations up to 3000 ng/ml without prior dilution while the IMx AFP assay requires dilution of samples with AFP concentrations of greater than 350 ng/ml. The ACCESS Immunoassay Analyzer stores reagents on board for up to 24 different analytes and has 28 day calibration curve stability, while Abbott IMx AFP assay is an individual analyte reagent kit.
6. -Summary of Studies
