Intended Use
The MESACUP TEST PR-3 is a semi-quantitative, enzyme-linked immunosorbent assay (ELISA) for the detection of IgG anti-proteinase III (PR-3) antibodies in human serum. The MESACUP TEST PR-3 is intended for in vitro diagnostic use as an aid in the diagnosis of certain systemic vasculitides such as Wegener's granulomatosis.
Device Description
The MESACUP Test PR-3 is an enzyme-linked immunosorbent assay (ELISA), utilizing the 96-microwell plate format, similar to the predicate device. Diluted serum samples, calibrator sera, and controls are incubated in microwells coated with proteinase III antigen. Incubation allows the anti-PR-3 antibodies present in the samples to react with the immobilized antigen. After the removal of unbound serum proteins by washing, antibodies specific for human IgG immunoglobulins, labeled with horseradish peroxidase (HRP), are added forming complexes with the PR-3 bound antibodies. Following another washing step, The bound enzyme-antibody conjugate is assayed by the addition of a single solution containing tetramethylbenzidine (TMB) and hydrogen peroxide (H2O2) as the chromogenic substrate, The intensity of the color generated is proportional to the serum concentration of anti-PR-3 antibodies, Optical density is read spectrophotometrically at 450mm. The total incubation time (at room temperature) of the assay is 150 minutes. The assay makes use of two calibrators to measure the amount of anti-PR-3 antibody in patient samples.

No
The description details a standard ELISA assay with spectrophotometric reading and comparison to calibrators, with no mention of AI or ML techniques for analysis or interpretation.

No.
The device is described as an in vitro diagnostic device, not one used for treatment or therapy. It aids in diagnosis, but does not treat the condition.

Yes

Explanation: The "Intended Use / Indications for Use" section explicitly states, "The MESACUP TEST PR-3 is intended for in vitro diagnostic use as an aid in the diagnosis of certain systemic vasculitides such as Wegener's granulomatosis."

No

The device is an in vitro diagnostic (IVD) kit that utilizes a physical ELISA assay with reagents and a microwell plate. While it involves reading optical density spectrophotometrically, the core of the device is a chemical and biological assay, not solely software.

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

Here's why:

  • Intended Use/Indications for Use: The description explicitly states "The MESACUP TEST PR-3 is intended for in vitro diagnostic use as an aid in the diagnosis of certain systemic vasculitides such as Wegener's granulomatosis." This directly indicates its purpose is for diagnostic testing performed outside of the body.
  • Device Description: The description details an enzyme-linked immunosorbent assay (ELISA) which is a common laboratory technique used for in vitro testing of biological samples (human serum in this case).
  • Intended User/Care Setting: The device is intended to be used by "clinical (hospital and reference) laboratories," which are typical settings for performing in vitro diagnostic tests.

All of 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)

Performance indicates that MESACUP Test PR-3 and the Bindazyme Human Anti-PR3 Enzyme Immunoassay are equivalent. In-house studies indicate a clinical specificity of 100% for anti-PR-3 antibodies in a healthy donor serum population on both kits. Additional studies resulted a sensitivity of 35% with a vasculitis population on both assay for anti-PR-3 antibadies compared to IIF ANCA positive results and 87% for both assays specifically for cANCA positive IIF petterns. In general, the performance characteristics are comparable between the two methods (100% relative agreement).

§ 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).
