MULTIPLE CHOICE
1. What test is used to screen for carbohydrate malabsorption?
a. Stool pH
b. Urine ketones
c. C urea breath test
d. ELISA stool assay
ANS: A
The anticipated pH of a stool specimen is 7.0. A stool pH of less than 5.0 is indicative of
carbohydrate malabsorption. The bacterial fermentation of carbohydrates in the colon produces
short-chain fatty acids, which lower the stool pH. Urine ketones detect the presence of ketones in
the urine, which indicates the use of alternative sources of energy to glucose. The C urea breath
test measures the amount of carbon dioxide exhaled. It is used to determine the presence of
Helicobacter pylori. ELISA (enzyme-linked immunosorbent assay) edcets the presence of
antigens and antibodies. It is not useful for disorders of metabolism.
