WHAT IS FRUCTOSE CHALLENGE TEST?
Fructose disorders all are inherited as autosomal recessive traits. Essential fructosuria is a clinically benign disorder. Fructose-1,6-diphosphatase deficiency is a clinically severe and often terminal illness in the newborn that is frequently diagnosed by clinical clues that do not involve fructose-loading tests. Hereditary fructose intolerance is a disorder, seen in children as well as adults, that is caused by a deficiency of fructose-1-phosphate aldolase. This condition, characterised by an aversion to sweet foods, may be diagnosed by use of the intravenous fructose challenge test. In this test, a weight-based dose of intravenous fructose is administered intravenously, and serial blood and urine samples are obtained.
