It is called Lactose Tolerance Test. The test consists of two hours after drinking a liquid that contain high level of lactose. The blood will be taken after drinking the fluid to test the amount of glucose in your bloodstream. If your level doesn’t rise, means that your body is not digesting and absorbing the lactose. Therefore, it is a positive test. Thank you.
Not sure. Ask your primary care provider.

A lactose breath test is a good way to support the clinical diagnosis of lactose intolerance.
