title: Radioimmunoassay of serum myoglobin in neuromuscular diseases.
abstract: Radioimmunoassay of serum myoglobin was performed in 85 patients with muscular symptoms. Elevated levels were found in 93% of patients with myogenic myopathy, in 54% with myasthenia gravis and in 50% with neurogenic myopathy. All 11 patients with polymyositis had elevated myoglobin concentrations. In six of seven patients with polymyositis, who were followed up with repeated determinations, a clear relationship between myoglobin levels and clinical course was found. In general serum myoglobin seemed to be a more sensitive indicator of muscle disease than creatine kinase.
