When to get tested?
Faecal Reducing Substances may be ordered by your doctor for symptoms suggestive of lactose intolerance, for example frequent loose stools, particularly if they are frothy in nature. Lactose intolerance may occur after a prolonged episode of viral gastroenteritis, due to inadequate absorption of the sugar lactose by a damaged intestinal lining. Other conditions, in which other sugars, such as glucose, galactose and fructose are not absorbed properly, can also cause a positive test for reducing sugars in the stool.
