Special instructions

Call and book appointment to have samples taken. Fast 8 - 10 hrs prior to sample being taken. Do not consume alcohol 24 hrs before test or cease prescribed medication without consulting your Doctor.
In a lactose tolerance test, you'll be given a drink of lactose solution and a blood sample will be taken from your arm using a needle. The blood will be tested to see how much glucose (blood sugar) it contains. Lactose is a sugar composed of two simple sugars joined together.

Lactose is found in milk and many other dairy products. Before it can be absorbed and used by the body it must be broken down by the enzyme lactase into two simpler sugars, glucose and galactose.

This lactose tolerance test looks for changes in the level of glucose in the blood after a drinking a lactose solution, to determine if the body can digest lactose properly. If you're lactose intolerant, your blood sugar levels will either rise slowly, or not at all due to the body not being able to break down the lactose into glucose. Increasing blood glucose levels over the course of the test indicates that signs and symptoms are unlikely to be due to lactose intolerance.
