<prompt> Answer this question truthfullyWhat are the laboratory results associated with Wilsons disease?  <response>: <reason> Laboratory tests are important in cases presenting with impaired liver functions and neurological impairment which increase suspicion against Wilsons disease. Liver function tests show nonspecific increase of the liver enzymes aspartate transaminase and alanine transaminase. The bilirubin is elevated as well. The following laboratory test are recommended to diagnose Wilsons disease: Ceruloplasmin level Serum copper concentration Urinary excretion of the copper 24hr monitoringMost of the patients with Wilsons disease will show a low serum level of ceruloplasmin less than 20mgdl. However, low ceruloplasmin level only is not sufficient for provisional diagnosis of Wilsons disease. Low ceruloplasmin level in patients whose examination shows Kayser-Fleischer ring and neurologic manifestations is diagnostic for Wilsons disease.Patients with Wilsons disease will have high level of total body concentration of the copper regardless the copper overload.In patients suspected with Wilsons disease, the urine should be collected for 24 hours in order to be examined for the copper concentration. Copper level in urine more than 100 μg24h is suggestive for Wilsons disease. However, it is not specific for Wilsons disease and may be elevated in other diseases as autoimmune hepatitis and cholestasis.In patients with Wilsons disease, liver function testing will be abnormal. This includes AST, ALT, total bilirubin, and alkaline phosphatase.
