Test ID: GALTP
Galactose-1-Phosphate Uridyltransferase Biochemical Phenotyping, Erythrocytes
Secondary ID 
A test code used for billing and in test definitions created prior to November 2011
Useful For Suggests clinical disorders or settings where the test may be helpful
Determining the biochemical phenotype for galactosemia when enzymatic and molecular results are incongruent
A quantitative GALT level (GALT/8333 Galactose-1-Phosphate Uridyltransferase [GALT], Blood) is used in addition to the isoelectric focusing for accurate interpretation
Genetics Test Information Provides information that may help with selection of the correct test or proper submission of the test request
Isoelectric focusing only; GALT/8333 Galactose-1-Phosphate Uridyltransferase (GALT), Blood must also be ordered.
See GCT/84360 Galactosemia Reflex, Blood for comprehensive diagnostic testing, carrier testing, and follow up of abnormal newborn screening results.
Additional Tests Lists test(s) that are always performed, at an additional charge, with the initial test(s)
| Test ID | Test Number | Reporting Name | Available Separately | Always Performed |
|---|---|---|---|---|
| GALT | 8333 | Gal-1-P Uridyltransferase, RBC | Yes | Yes |
Testing Algorithm Delineates situation(s) when tests are added to the initial order. This includes reflex and additional tests.
A quantitative galactose-1-phosphate uridyltransferase (GALT) level (GALT/8333 Galactose-1-Phosphate Uridyltransferase [GALT], Blood) is used in addition to the isoelectric focusing for accurate interpretation. If GALT has not been done previously, it must be ordered at an additional charge.
