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). ## Classification Rationale Class II (performance standards). ## Recent Cleared Devices (20 of 50) Showing 20 most recent of 50 cleared devices. | Record | Device Name | Applicant | Decision Date | Decision | | --- | --- | --- | --- | --- | | [K210902](https://fda.innolitics.com/submissions/IM/subpart-f%E2%80%94immunological-test-systems/LKJ/K210902.md) | EliA Ro52, EliA Ro60 | Phadia AB | Jul 27, 2022 | SESE | | [K113610](https://fda.innolitics.com/submissions/IM/subpart-f%E2%80%94immunological-test-systems/LKJ/K113610.md) | ANA-SCREEN WITH MDSS | Bio-Rad Laboratories | Jul 9, 2012 | SESE | | [K082759](https://fda.innolitics.com/submissions/IM/subpart-f%E2%80%94immunological-test-systems/LKJ/K082759.md) | ELIA CENP IMMUNOASSAY, ELIA U1RNP IMMUNOASSAY, ELIA SM IMMUNOASSAY, ELIA RO IMMUNOASSAY | Phadia US, Inc. | Apr 10, 2009 | SESE | | [K081104](https://fda.innolitics.com/submissions/IM/subpart-f%E2%80%94immunological-test-systems/LKJ/K081104.md) | AESKULISA ANA HEP-2, REF 30-7115US | Aesku Diagnostics | May 2, 2008 | SESE | | [K041658](https://fda.innolitics.com/submissions/IM/subpart-f%E2%80%94immunological-test-systems/LKJ/K041658.md) | BIOPLEX 200 ANA SCREEN ON THE BIOPLEX 2200 MULTI-ANALYTE DETECTION SYSTEM, MODEL BIOPLEX 2200 | Bio-Rad Laboratories, Inc. | Dec 20, 2004 | SESE | | [K042416](https://fda.innolitics.com/submissions/IM/subpart-f%E2%80%94immunological-test-systems/LKJ/K042416.md) | ATHENA MULTI-LYTE ANA-II TEST SYSTEM | Zeus Scientific, Inc. | Oct 8, 2004 | SESE | | [K034013](https://fda.innolitics.com/submissions/IM/subpart-f%E2%80%94immunological-test-systems/LKJ/K034013.md) | REAADS DSDNA QUANTITATIVE TEST KIT, MODEL 022-001 | Corgenix, Inc. | Jan 8, 2004 | SESE | | [K030775](https://fda.innolitics.com/submissions/IM/subpart-f%E2%80%94immunological-test-systems/LKJ/K030775.md) | AUTO I.D.
