The summary describes a radioimmunoassay (RIA) kit for detecting antibodies, which is a standard laboratory technique and does not mention or imply the use of AI or ML.
No
The device is an assay kit designed for diagnostic purposes (determining antibodies for autoimmune adrenal disease), not for treating or preventing disease.
Yes
The intended use explicitly states that the assay "may be useful as an aid in the diagnosis of autoimmune adrenal disease."
No
The device is a RIA Assay Kit, which is a laboratory test kit containing reagents and likely other physical components for performing a radioimmunoassay. This is not a software-only device.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states that the kit is for the "semiquantitative determination of antibodies to steroid 21-hydroxylase (21-OH) in human serum." This involves testing a biological sample (human serum) outside of the body to gain information about a person's health status.
- Aid in Diagnosis: The intended use also states that the assay "may be useful as an aid in the diagnosis of autoimmune adrenal disease." This directly aligns with the purpose of IVDs, which are used to diagnose, monitor, or screen for diseases or conditions.
- Sample Type: The assay uses "human serum," which is a common biological sample used in IVD testing.
The definition of an IVD generally includes devices intended for use in the examination of specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device fits that description perfectly.

Intended Use / Indications for Use
The KRONUS 21-Hydroxylase Antibody (21-OHAb) RIA Assay Kit is for the semiquantitative determination of antibodies to steroid 21-hydroxylase (21-OH) in human serum. The KRONUS Steroid 21-OHAb RIA Assay may be useful as an aid in the diagnosis of autoimmune adrenal disease, whether expressed as autoimmune Addison's disease (isolated) or Addison's disease as part of the more complex autoimmune polyglandular syndrome (APS), type I or II. The assay result is to be used in conjunction with other clinical and laboratory findings and is not a substitute for functional testing required to diagnose adrenal insufficiency.

§ 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).

Dear Ms. Jimenez:
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 udications 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 FederallFound, Dr 10 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. Please note: CDRH does not evaluate information related to contractly allity warranties. We remind you, however, that device labeling must be truthful and not micleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls.
