Repeat Testing of Antibodies and Complements in Systemic Lupus Erythematosus: When Is It Enough?

CONCLUSION: Anti-ENA results change infrequently, especially following 1 or more negative tests. The high cost and lack of evidence that changes affect management suggest that repeating anti-ENA tests routinely is unnecessary. Anti-dsDNA and complements change more frequently after an abnormal result, but less after a normal value.
