Screening test for galactosemia in urine specimens

Highlights

Galactose-1-phosphate uridyltransferase (GALT) deficiency is the most common cause of galactosemia and requires lifelong restriction of dietary galactose.

 

Urine galactose can be elevated in patients with galactosemia caused by either galactose-1-phosphate uridyltransferase (GALT) deficiency or galactokinase (GALK) deficiency.

 

Classic galactosemia can be diagnosed by analysis of GALT enzyme.

Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.

This test is not appropriate for the diagnosis or monitoring of galactosemia. For diagnosis, see GCT / Galactosemia Reflex, Blood. For monitoring, see GAL1P / Galactose-1-Phosphate (Gal-1-P), Erythrocytes.
