More Information

Not Found

No
The summary describes a turbidimetric assay for measuring complement C4, which is a standard laboratory technique and does not mention any AI or ML components.

No.
The device is described as an "in vitro diagnostic test intended to quantitatively measure complement C4 (C4) in serum as an aid in the diagnosis of immunologic disorders." It is used for diagnosis, not treatment.

Yes
The C4 Flex® reagent cartridge is explicitly stated as an "in vitro diagnostic test intended to quantitatively measure complement C4 (C4) in serum as an aid in the diagnosis of immunologic disorders." This clearly indicates its purpose in diagnosing medical conditions.

No

The device is a reagent cartridge, which is a physical component used in a clinical chemistry system, not a software-only device.

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

Here's why:

  • Intended Use: The "Intended Use / Indications for Use" section explicitly states that the device is an "in vitro diagnostic test intended to quantitatively measure complement C4 (C4) in serum". This is the primary characteristic of an IVD.
  • Device Description: The description details a "quantitative, turbidimetric assay using endpoint detection, based on the precipitation of complement C4 by its polyclonal antibody." This describes a laboratory test performed on a biological sample (serum) outside of the body, which is consistent with an in vitro diagnostic.
  • Predicate Devices: The listing of predicate devices (K780913 and K922273, which are also likely IVDs) further supports its classification as an IVD.

The information provided clearly indicates that this device is designed to be used in a laboratory setting to analyze a biological sample (serum) to provide diagnostic information, which is the definition of an In Vitro Diagnostic device.

§ 866.5240 Complement components immunological test system.

(a)
Identification. A complement components immunological test system is a device that consists of the reagents used to measure by immunochemical techniques complement components C1q , C1r , C1s , C2 , C3 , C4 , C5 , C6 , C7 , C8 , and C9 , in serum, other body fluids, and tissues. Complement is a group of serum proteins which destroy infectious agents. Measurements of these proteins aids in the diagnosis of immunologic disorders, especially those associated with deficiencies of complement components.(b)
Classification. Class II (performance standards).
