Quizplus · Accepted Answer

The lactose-tolerance test involves administering a measured amount of lactose (usually 50 g) in a small amount of water and then measuring the patient's blood glucose levels at certain intervals to see how well their body is able to digest and absorb the lactose. Collecting a stool specimen or having the patient drink a glass of whole milk are not appropriate methods for this test. Injecting lactose intravenously is not a recommended method for this test and could be dangerous.
