Useful For Suggests clinical disorders or settings where the test may be helpful
Screening for disorders with increased excretion of fructose, glucose, galactose, disaccharides, oligosaccharides, and succinylpurines
Genetics Test Information Provides information that may help with selection of the correct test or proper submission of the test request
Screening for disorders with increased excretion of fructose, glucose, galactose, disaccharides, oligosaccharides, and succinylpurines. If qualitative result is suggestive of an elevation of galactose or glucose, quantitative testing will be performed at an additional charge.
Reflex Tests Lists test(s) that may or may not be performed, at an additional charge, depending on the result and interpretation of the initial test(s)
| Test ID | Reporting Name | Available Separately | Always Performed |
|---|---|---|---|
| GALU | Galactose, QN, U | Yes | No |
| RGLUR | Glucose, Random, U | Yes | No |
Testing Algorithm Delineates situation(s) when tests are added to the initial order. This includes reflex and additional tests.
Testing begins with CHOU/9255 Carbohydrate, Urine. If qualitative results are normal, or abnormal but not indicative of galactose or glucose, testing is complete.
If qualitative results indicate the presence of galactose, GALU/8765 Galactose, Quantitative, Urine will be performed at an additional charge.
If qualitative results indicate the presence of glucose, RGLUR/89847 Glucose, Random, Urine will be performed at an additional charge.
