Some drugs and infections as well as other conditions can give a false positive result for the ANA test. Some (but not all) of these drugs may bring on a condition that includes SLE symptoms, called drug-induced SLE-like syndrome. When the drugs are stopped, the symptoms usually go away. Although many medications have been reported to cause drug-induced lupus, those most closely associated with this syndrome include hydralazine, isoniazid, procainamide, and several anticonvulsants.
