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 genetic 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 tests that may or may not be performed, at an additional charge, depending on the result and interpretation of the initial tests.

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

Testing begins with carbohydrate analysis. 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, then quantitative testing for galactose will be performed at an additional charge.

If qualitative results indicate the presence of glucose, then random glucose testing will be performed at an additional charge.
