TWO TYPES OF SITUATIONS: Measurement of transaminase serum activity is a common biological test. Although the etiological scope of acute and severe hyper-aminotransferase is codified and limited, that of prolonged and moderate hyper-aminotransferase is much broader. IN THE CASE OF PROLONGED AND MODERATE INCREASE IN TRANSAMINASE SERUM ACTIVITY: The discovery of this abnormality during systematic biological controls is a frequent situation, and its management is relatively well standardised. It requires a rigorous diagnostic strategy, which includes the search for consumption of alcohol, overweight, chronic hepatic disease of viral origin and the nature of the medicinal products ingested. FROM AN ETIOLOGICAL POINT OF VIEW: The most frequent causes of moderate and prolonged hyper-aminotransferase are alcohol abuse, overweight, non-insulin-dependent diabetes, dyslipaemia, viral hepatitis and medicinal products. However, less frequent hepatic or extra-hepatic causes must not be neglected.
