Hydrogen breath test

A possible lactose intolerance test that is administered in some hospitals is a hydrogen breath test. This involves measuring hydrogen in the exhaled air. This is done both before drinking a sugar solution containing lactose and after drinking this sugar solution (3 hours later). This lactose intolerance test is conducted in this way to determine whether or not the intestine can digest lactose properly. The hydrogen breath test is performed in the hospital under the supervision of a specialist.

Lactose intolerance test

In this test, before and after drinking a lactose solution blood taken to measure blood sugar levels to measure. If the milk sugar is digested, it is absorbed into the bloodstream and the blood sugar level rises. If the milk sugar is not absorbed, the blood sugar level will not rise. This is known as lactose intolerance. 

Elimination-provocation test

A third test that is often performed is the elimination-provocation test. This test is often done in consultation with a dietitian. It involves not consuming any products containing lactose for a certain period of time. This is called ‘elimination’. After this period, a certain amount of lactose is added to this ‘diet’. If the person reacts to this, a diagnosis of ’lactose intolerance’ is made.
