Task: Answer Verification
Input (English): Question: Are elevated levels of serum carbohydrate deficient transferrin specific for alcohol abuse in patients with liver disease?
Answer: Thus, in a patient with a negative interview for chronic alcohol abuse and normal carbohydrate deficient transferrin level, alcohol is unlikely to be the cause of liver disease, and further investigations to establish the etiology of liver disease are warranted. An increased carbohydrate deficient transferrin level, however, cannot be regarded as reliable evidence for chronic alcohol abuse in patients with liver disease.
Output (English): no
