SERUM LACTOSE TOLERANCE

Lactose tolerance tests measure your body's ability to break down lactose. Lactose is a type of sugar found in milk, cheese, ice cream, and other dairy products. Normally, an enzyme called lactase breaks down lactose into simpler sugars. These sugars are absorbed by the body and turned into energy. If your body doesn't make enough lactase, you won't be able to properly digest foods that contain lactose. This is known as lactose intolerance.
