The description details a standard indirect fluorescent antibody assay using microscopy, with no mention of AI/ML in the device description, intended use, or performance studies.
No
The device is an in vitro diagnostic (IVD) device used to aid in the diagnosis of autoimmune diseases by detecting antinuclear antibodies, not to treat or alleviate a disease or condition.
Yes
Explanation: The "Intended Use / Indications for Use" section states that the device is "intended for use as an aid in the diagnosis of certain autoimmune diseases."
No
The device description clearly outlines a laboratory assay involving physical components like substrate slides, serum samples, reagents, and a fluorescence microscope, indicating it is a hardware-based diagnostic test system, not software-only.
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 for the "qualitative and/or semi-quantitative determination of antinuclear antibodies in human serum." This involves testing a sample taken from the human body (serum) outside of the body (in vitro).
- Device Description: The description details a laboratory assay process involving the incubation of serum samples with a substrate and the use of reagents to detect antibodies. This is a typical in vitro diagnostic procedure.
- Intended User / Care Setting: The device is intended for use by "clinical (hospital and reference) laboratories," which are settings where in vitro diagnostic tests are performed.
The core function of the device is to analyze a biological sample (human serum) to provide information about a person's health status (presence of antinuclear antibodies as an aid in diagnosing autoimmune diseases), which is the definition of an in vitro diagnostic device.

Intended Use / Indications for Use
The HEP-ANA Test System is an indirect fluorescent antibody assay utilizing HEp-2 tissue culture cells as a substrate for the qualitative and/or semi-quantitative determination of antinuclear antibodies in human serum. The HEP-ANA Test System is intended for use as an aid in the diagnosis of certain autoimmune diseases.

Device Description
The RhiGene HEP-ANA Test System is an indirect fluorescent antibody assay utilizing HEp-2 tissue culture cells as a substrate, similar to the predicate device. Diluted serum samples are incubated on substrate slides coated with HEP-2 (human epithelial) cells. Incubation allows the anti-nuclear antibodies (ANA) present in the samples to react with the antigen. After the removal of unbound serum proteins by washing, antibodies specific for human immunoglobulins, labeled with fluorescein isothiocyanate (FITC), are added forming complexes with the nuclear bound antibodies. Following another washing step, coverslips are mounted and then the slides are examined with a fluorescence microscope. The total incubation time (at room temperature in a moist chamber) of the assay is 40 minutes.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Performance indicates that HEP-ANA Test system and the RhiGene Titer-Fluor ANA Test System are equivalent. In-house studies indicate a clinical specificity of 82% and 78% for ANA in a healthy donor serum population respectively. Additional studies resulted a sensitivity of 75% with an autoimmune diseases population on both assay. In general, the performance characteristics are comparable between the two methods. These results are also in compliance with those in published literature for ANA detection. The clinical studies performed demonstrate that the HEP-ANA test system is safe and effective.

§ 866.5100 Antinuclear antibody immunological test system.
(a)
Identification. An antinuclear antibody immunological test system is a device that consists of the reagents used to measure by immunochemical techniques the autoimmune antibodies in serum, other body fluids, and tissues that react with cellular nuclear constituents (molecules present in the nucleus of a cell, such as ribonucleic acid, deoxyribonucleic acid, or nuclear proteins). The measurements aid in the diagnosis of systemic lupus erythematosus (a multisystem autoimmune disease in which antibodies attack the victim's own tissues), hepatitis (a liver disease), rheumatoid arthritis, Sjögren's syndrome (arthritis with inflammation of the eye, eyelid, and salivary glands), and systemic sclerosis (chronic hardening and shrinking of many body tissues).(b)
Classification. Class II (performance standards).
