Quizplus · Accepted Answer

The hydrogen breath test is the most commonly used laboratory test for diagnosing lactose intolerance. This test involves drinking a lactose solution and measuring the levels of hydrogen gas in the breath. If there is an increase in hydrogen levels, it suggests that undigested lactose is fermenting in the intestine and producing hydrogen gas. This indicates a possible diagnosis of lactose intolerance.
