The EUROIMMUN IFA: Crithidia luciliae (anti-dsDNA) EUROPattern test kit is intended for the quantitative determination of human antibodies of immunoglobulin class IgG against anti-double stranded DNA (dsDNA) in human serum with the EUROPattern Microscope and Software automated instrument. It is used as an aid in the diagnosis of systemic lupus erythematosus (SLE), in conjunction with other laboratory and clinical findings. All suggested results obtained with the EUROPattern system must be confirmed by trained personnel.
Not Found
The provided text is a U.S. FDA 510(k) clearance letter for the EUROIMMUN IFA: Crithidia luciliae (anti-dsDNA) EUROPattern test kit. This document primarily focuses on regulatory approval and indications for use, stating that the device is substantially equivalent to legally marketed predicate devices.
However, the letter does NOT contain the detailed information about acceptance criteria or the specific study that proves the device meets those criteria, as typically found in a clinical study report or a more comprehensive submission document.
Therefore, I cannot provide the requested information from the provided text. The document does not include:
- A table of acceptance criteria and reported device performance.
- Sample sizes for test sets, data provenance, or details about training sets.
- Information about experts, ground truth establishment, or adjudication methods.
- Details about MRMC studies, effect sizes, or standalone algorithm performance.
To provide the requested information, you would typically need to refer to the device's 510(k) summary, the full 510(k) submission, or relevant clinical study publications, which are not included in this document.
§ 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).
