Lactose intolerance is diagnosed by which of the following tests?
  1. Breath hydrogen test
  2. Lactose tolerance test
  3. Blood lactase test
  4. A & B
Explanation
Answer: D - Lactose intolerance is diagnosed by a breath hydrogen test, which measures hydrogen produced by the action of intestinal bacteria on lactose, or by the lactose tolerance test, which involves the oral administration of lactose, followed by a blood test measuring blood glucose. A flat blood glucose curve indicates lactose intolerance, due to the body’s inability to break down lactose into glucose and galactose.
