Serum ceruloplasmin concentration is obtained as a screening test for Wilson disease in patients younger than 40 years who present with parkinsonian signs. If the ceruloplasmin level is low, measurement of 24-hour urinary copper excretion and slit-lamp examination for Kayser-Fleischer rings must be performed. Abnormal results on urinary sphincter electromyography have been noted in patients with multiple system atrophy (MSA).
