Patients with drug-induced lupus erythematosus typically have positive tests for anti-histone antibodies but do not have indications for anti-dsDNA antibodies. Patients with idiopathic systemic lupus erythematosus have both types of autoantibodies present in their blood. Thus, this test can be useful in distinguishing these two illnesses. [9]
