For patients with kidney disease, a positive antinuclear antibody (ANA) test generally suggests the possibility of an autoimmune disorder. Patients with nephritis should be evaluated for lupus nephritis and screened for systemic lupus erythematosus. Additionally, ANA positivity can also occur in conditions such as tuberculosis and malignancies. However, a positive ANA result does not necessarily mean the patient has one of these diseases, as ANA test results may be influenced by various factors. Therefore, interpreting a positive ANA result requires comprehensive evaluation in conjunction with the patient's clinical context.
