Reducing substance by the Clinitest method is no longer performed on infants less than two years of age.
Today, all states require mandatory newborn screening for more than 30 inborn errors of metabolism. This testing detects galactosemia, which is the most common inborn error of carbohydrate metabolism. Other diseases of carbohydrate metabolism (except diabetes) have much lower prevalence or are clinically more benign than galactosemia and do not require screening of asymptomatic newborns.
Based on this information, Legacy Laboratory has discontinued Clinitest reflex testing.
