Don’t test ANA sub-serologies without a positive ANA and clinical suspicion of immune-mediated disease.

Tests for anti-nuclear antibody (ANA) sub-serologies (including antibodies to double-stranded DNA, Smith, RNP, SSA, SSB, Scl-70, centromere) are usually negative if the ANA is negative. Exceptions include anti-Jo1, which can be positive in some forms of myositis, or occasionally, anti-SSA, in the setting of lupus or Sjögren’s syndrome. Broad testing of autoantibodies should be avoided; instead the choice of autoantibodies should be guided by the specific disease under consideration.

How The List Was Created

The American College of Rheumatology (ACR) established a Top 5 Task Force to oversee the creation of its recommendations. As part of this group’s work, a multistage process combining consensus methodology and literature reviews was used to arrive at the final recommendations. Items were generated by a group of practicing rheumatologists in diverse clinical settings using the Delphi method. Recommendations with high content agreement and perceived prevalence advanced to a survey of ACR members, who comprise more than 90% of the U.S. rheumatology workforce. Based on member input related to content agreement, impact and item ranking, candidate items advanced to literature review. The Top 5 Task Force discussed the items in light of their relevance to rheumatology, level of evidence to support their inclusion, and the member survey results, and drafted the final rheumatology Top 5 list. The list was reviewed by a sample of patients with rheumatic disease and approved by the ACR Board of Directors.
