![]() ![]() Positive predictive values for a positive ANA test result were calculated for all antinuclear antibody-associated rheumatic diseases and for lupus specifically. All relevant descriptive and laboratory data were collated, as were the initial reasons for ordering ANA testing and the ultimate diagnoses reached. METHODS: We reviewed the records of patients presenting to the authors between July 2007 and July Patients were included in the evaluation if they were referred for a positive ANA test result. The purpose of this investigation was to evaluate the clinical utility of a positive ANA test result in a real-world setting by reviewing the final diagnoses of patients who were referred to a tertiary rheumatology clinic for evaluation of a positive ANA test result. Prior studies have investigated the frequency of ANA positivity within the general population. ![]() ABSTRACT BACKGROUND: This retrospective study investigated the clinical utility of a positive antinuclear antibody (ANA) test performed outside of the rheumatology setting.
