[Abnormal hepatic function tests in pregnancy: causes and consequences].

The well-known normal ranges of laboratory parameters are altered due to the broad spectrum of physiological changes as well as proinflammatory and procoagulant effects of pregnancy. Hepatic disorders of any aetiology can cause potential problems during gravidity. Most frequently toxic-effects, hepatotrop viruses (such as hepatitis B and C), metabolic syndrome and diseases with autoimmune background can be observed. When dealing with "pregnancy-specific hepatic syndromes", it is very important to consider the "timing-factors" of pathologic changes and deterioration of clinical pictures as well. Due to the progress in cholestasis management, early termination of pregnancy can be avoided in many cases. As the overlap is really broad between various hepatic disorders, a multidisciplinary cooperation of different sub-disciplines is emphasized in order to achieve proper diagnosis and curative measures at early phase.
