Background/Purpose: ANA test is a commonly used initial screening for connective tissue diseases (CTD). The ultimate clinical utility of this highly sensitive test depends on the pretest diagnostic probability. It should not be a first line test for the investigation of musculoskeletal symptoms like fatigue or joint pains, unless accompanied by other clinical features to suggest autoimmune disease. It can be positive in multiple autoimmune and mixed connective tissue disorders. It can also be falsely positive in multiple other scenarios. ANA test rarely needs to be repeated. It is a diagnostic, not monitoring test. If an unexpected result is given, it is reasonable to repeat the test to confirm the finding. It is also useful to repeat if a person’s illness has significantly changed. It, however, has no correlation to disease activity in SLE or other CTD. A trend of repeating ANA testing on patients with a history of positive ANA was noted in our outpatient multispecialty clinic. The purpose of this study is to review how frequently patients with known positive ANA testing undergo repeat ANA testing, the reason for it and the specialty and level of training of providers ordering it.
Conclusion: Further education and emphasis should be given on appropriate ANA testing criteria in order to decrease misuse and increase cost effectiveness.
