Isolierte Erhöhung der γGT: Was ist diagnostisch erforderlich?

Summary An isolated elevation of γGT can be found in pre-, intra- or posthepatic dysfunction, but also in endocrine, renal and other disorders. History, physical examination, ultrasound and laboratory analysis constitute a basic work up which in individual cases can be extended. Liver biopsy is rarely necessary. Although prognosis is usually good, an isolated elevation of γGT can be an indicator of severe diseases.
