Abstract
Hypertransaminasemia is a relatively frequent problem observed in children. It can occur in the context of liver disease, but must of the times appears to be an accidental finding in a blood check test for other reasons.
Most patients can be managed in primary settings, but we must take into account several warning signs indicative of several liver diseases.
The employment of clinical protocols or guidelines such as the indicated in this paper may improve patient management in order to obtain adequate diagnosis ant to prevent unnecessary secondary tests and iatrogenia.
