No
The summary describes a standard enzyme immunoassay test system and does not mention any AI or ML components.
No
This device is an immunoassay test system used to detect antibodies for diagnostic purposes, not to treat a condition.
Yes
The device is an enzyme immunoassay test system for the detection of antibodies associated with specific medical conditions (Wegener's granulomatosis and other vasculitides), indicating its use in aiding diagnosis.
No
The device description clearly states it is an "enzyme immunoassay test system" and an "enzyme immunoassay," which are laboratory-based tests involving physical reagents and processes, not solely software.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use/Indications for Use: The description explicitly states it's a "test system for the detection of antibodies to Proteinase 3 (PR3) in human serum." This indicates it's used to analyze a sample taken from the human body (in vitro) to provide diagnostic information.
- Device Description: It's described as an "enzyme immunoassay for the detection of antibodies to Proteinase 3 (PR3) in human serum." This further confirms it's a laboratory test performed on a biological sample.
- Aid in Detection: The intended use states it's to be used as an "aid in the detection of antibodies associated with Wegener's granulomatosis and other vasculitides." This clearly links the test results to providing information for diagnosing or managing a medical condition.
These points align with the definition of an In Vitro Diagnostic device, which is used to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes.

Summary of Performance Studies
The Immuno Concepts RELISA® PR3 Test System was compared to the Bindazyme™ Anti-PR3 Enzyme Immunoassay Kit manufactured by The Binding Site, Ltd., Birmingham, England, UK. (K981029). The population studied consisted of 206 samples which were submitted to clinical laboratories for ANCA, MPO and PR3 testing, but without specific diagnoses, 7 samples which were from patients with a diagnosis of Churg-Strauss syndrome, 18 patients with a diagnosis of vasculitis, 25 patients with a diagnosis of Wegener's granulomatosis, 261 samples from male blood donors, and 239 samples from female blood donors. All samples were tested in parallel on the predicate device and the subject device.

§ 866.5660 Multiple autoantibodies immunological test system.
(a)
Identification. A multiple autoantibodies immunological test system is a device that consists of the reagents used to measure by immunochemical techniques the autoantibodies (antibodies produced against the body's own tissues) in serum and other body fluids. Measurement of multiple autoantibodies aids in the diagnosis of autoimmune disorders (disease produced when the body's own tissues are injured by autoantibodies).(b)
Classification. Class II (performance standards).

Date Prepared: July 23, 2001 Contact Person: Eric S. Hoy, Ph.D., SI(ASCP) Name of Device:
- · Trade Name RELISA® PR3-ANCA Test System for Antibodies to Proteinase 3
- · Common Name Anti-PR3 Antibody Enzyme Immunoassay Test Kit
- · Classification Name Test System, Antineutrophil Cytoplasmic Antibodies (ANCA) (21 CFR 866.5660)
Legally marketed device with which this device has been shown to be equivalent: Bindazyme™ Anti-PR3 Enzyme Immunoassay Kit manufactured by The Binding Site, Ltd., Birmingham, England, UK, K981029.
Description:
This is an enzyme immunoassay for the detection of antibodies to Proteinase 3 (PR3) in human serum.
Intended Use:
This is an enzyme immunoassay test system for the detection of antibodies to Proteinase 3 (PR3) in human serum. This test system is to be used as an aid in the detection of antibodies associated with Wegener's granulomatosis and other vasculitides.
Summary of Technological Characteristics Compared to the Predicate Device:
Technologically, this device is similar to the predicate device with the following exceptions:
a) The predicate device has all 96 microwells sealed in a single pouch. The present device has each eight well strip of microwells sealed in an individual pouch, so that unused wells remain in the pouches, and maintain at least 12 months stability.
b) The predicate device uses six calibrator sera, the present device uses five calibrator sera.

| RELISA® PR3-ANCA | |||
| Test System | Negative | 4 | 563 |
These data yield the following statistics: relative sensitivity, 97.8%; relative specificity, 98.6%; and overall agreement, 98.4%
Among the 8 "false positive" samples, 2 showed a P-ANCA pattern by immunofluorescence, 4 showed a C-ANCA pattern by immunofluorescence, and 2 did not demonstrate any immunofluorescent pattern. Two of the samples that showed a C-ANCA pattern by immunoflurescence and a positive RELISA® PR3 were from patients with a diagnosis of Wegener's granulomatosis, and one of the samples that showed a P-ANCA pattern by immunofluorescence and a positive RELISA® PR3 was from a patient with a diagnosis of Churg-Strauss syndrome. These samples may actually represent "false negative" results on the predicate device.
In accordance with 21 CFR 807.92(b)(3), we conclude from these data that the present device is substantially equivalent to the predicate device.
