No
The summary describes a standard immunoturbidimetric assay and does not mention any AI or ML components.
No
The device aids in diagnosis by measuring IgA levels, but it does not directly treat or prevent a disease, which is the function of a therapeutic device.
Yes
The device is described as an "immunoturbidimetric assay for the quantitative in vitro determination of IgA in human serum and plasma" and states that "Measurement aids in the diagnosis of abnormal protein metabolism and the body's lack of ability to resist infectious agents," directly implying a diagnostic purpose.
No
The device description clearly states it is an "immunoturbidimetric assay" which is a laboratory test method involving reagents and measurement of turbidity, indicating a physical/chemical process, not solely software.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use explicitly states it is an "in vitro determination of IgA in human serum and plasma." "In vitro" means "in glass" or "outside the body," which is a key characteristic of IVDs.
- Measurement Aids in Diagnosis: The intended use also states that the measurement "aids in the diagnosis of abnormal protein metabolism and the body's lack of ability to resist infectious agents." This indicates the device is used to provide information for diagnostic purposes.
- Device Description: The device description details an "immunoturbidimetric assay" that measures an antigen/antibody complex. This is a common method used in laboratory tests performed on biological samples outside the body.
- Sample Type: The assay uses "human serum and plasma," which are biological samples collected from a patient.
- Predicate Device: The mention of a predicate device (K955907; Roche Diagnostics Tina-quant IgA assay) further supports its classification as an IVD, as predicate devices are typically other legally marketed IVDs.
All of these points align with the definition and characteristics of an In Vitro Diagnostic device.

§ 866.5510 Immunoglobulins A, G, M, D, and E immunological test system.
(a)
Identification. An immunoglobulins A, G, M, D, and E immunological test system is a device that consists of the reagents used to measure by immunochemical techniques the immunoglobulins A, G, M, D, an E (serum antibodies) in serum. Measurement of these immunoglobulins aids in the diagnosis of abnormal protein metabolism and the body's lack of ability to resist infectious agents.(b)
Classification. Class II (performance standards).

Dear Ms. Coenen:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in Title 21, Code of Federal Regulations (CFR), Parts 800 to 895. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Parts 801 and 809); and good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820). This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
