Testing begins with galactose-1-phosphate uridyltransferase (GALT) enzyme analysis. If GALT is > or =24.5 nmol/h/mg of hemoglobin, testing is complete. No molecular test will be performed. If GALT is <24.5 nmol/h/mg of hemoglobin, GAL14 / Galactosemia Gene Analysis (14-Mutation Panel) will be performed at an additional charge.
See Galactosemia Testing Algorithm in Special Instructions.
