Stool Acidity Test
For children and infants who cannot undergo these diagnostic tests above, a stool acidity test can be a good option. All the doctor needs is a stool sample on a special kit. It will be tested in the lab to find out any signs of the condition. When lactose cannot be digested and absorbed by the body, it will increase the level of lactic acid in the stool. Therefore, the result of this test can indicate the presence of lactose caused by the disease. [5]
