[Hereditary abnormalities of galactose metabolism: diagnosis and biochemical supervision (author's transl)]

The authors define the main stages of the biochemical study of hereditary abnormalities of galactose metabolism. They review laboratory examinations for detection, enzyme examinations which provide the diagnostic proof, further examinations which permit one to follow the course and efficacy of a galactose-free diet, the demonstration of genetic variants, the technics of antenatal diagnosis and routine neonatal detection.
