|Key Information||Appropriate Tests|
Galactose-1-phosphate uridyl transferase - red cell, galactose-1-phosphate - red cell.
Reducing substances - urine: galactose in urine will give a positive result, but the test is insensitive and a negative result does not exclude the possibility of galactosaemia.
Neonatal screen positive
The result must be validated by follow up assays (red cell galactose-1-phosphate uridyl transferase and galactose-1-phosphate) to exclude false positives, to define mild, non-pathogenic variants and to distinguish galactokinase deficiency.See also Neonatal screening
