Interpretation: In patients with galactosemia, elevated galactose in plasma or urine may suggest<br />

ineffective dietary restriction or compliance; however, the concentration of galactose-1-phosphate in<br />

erythrocytes (GAL1P/80337 Galactose-1-Phosphate [Gal-1-P], Erythrocytes) is the most sensitive index<br />

of dietary control. Increased concentrations of galactose may also be suggestive of severe hepatitis, biliary<br />

atresia of the newborn, and, in rare cases, galactose intolerance. If galactosemia is suspected, additional<br />

testing to identify the specific enzymatic defect is required. See Galactosemia <strong>Test</strong>ing Algorithm in<br />

Special Instructions for follow-up of abnormal newborn screening results, comprehensive diagnostic<br />

testing, and carrier testing. See GALT/8333 Galactose-1-Phosphate Uridyltransferase (GALT), Blood for<br />

GALT testing and GALK/8628 Galactokinase, Blood for GALK testing. Uridine diphosphate<br />

galactose-4-epimerase (GALE) enzyme testing is not available at <strong>Mayo</strong> <strong>Medical</strong> Laboratories; upon<br />

request, specimens will be forwarded to an external laboratory. Results should be correlated with clinical<br />

presentation and confirmed by specific enzyme or molecular analysis.<br />
