Use

Screening for conditions associated with increased excretion of carbohydrates, including inborn errors of fructose and galactose metabolism. The identification and quantitation of carbohydrates, particularly galactose and fructose, is useful to screen for inborn errors of metabolism such as galactosemia and hereditary fructose intolerance. The presence of carbohydrates in urine can also indicate specific pathological conditions or dietary consumption. This test is useful as an initial screen and abnormal results require further confirmation by enzyme assays, molecular genetic analysis, or correlation with other laboratory testing.
