Lactose Tolerance Test

Three reasons the Lactose Tolerance test is right for you

• This test assesses how well your body processes lactose, the natural sugar found in dairy products
• It helps diagnose lactose intolerance as a cause of digestive symptoms
• Results support dietary planning to reduce discomfort and improve digestive health

What is the Lactose Tolerance test?

The Lactose Tolerance test measures how effectively your body digests lactose. Lactose is a sugar found in milk and other dairy products. To digest lactose properly, your body needs an enzyme called lactase. If lactase levels are low, lactose intolerance can develop, leading to digestive symptoms after consuming dairy.

This test is often recommended for:

• Individuals experiencing bloating, gas, or diarrhoea after consuming dairy products
• People with unexplained abdominal discomfort
• Patients seeking confirmation of suspected lactose intolerance
• Those wanting to differentiate lactose intolerance from other gastrointestinal conditions

What are the symptoms of lactose intolerance?

Symptoms usually occur within a few hours of consuming dairy products and may include:

• Abdominal bloating or cramping
• Diarrhoea
• Excess gas
• Nausea
• Stomach discomfort after milk or dairy consumption

How does the Lactose Tolerance test work?

The test typically involves measuring your blood glucose levels before and after consuming a lactose-containing drink. If your body properly digests lactose, blood glucose levels will rise. If not, this may indicate lactose intolerance.

Multiple blood samples may be taken over a set period to assess how your body responds.

What can I expect at my appointment?

Your appointment will involve an initial blood sample, followed by drinking a lactose solution. Additional blood samples will be collected at timed intervals to measure your body’s response.

The process may take a few hours to complete. Results are usually available within a few days, and your report will help determine whether lactose intolerance is likely.

Are there any risks with this test?

This is a safe and routine diagnostic test. You may experience temporary digestive discomfort during the test if you are lactose intolerant.

As with any blood test, minor bruising or tenderness at the needle site may occur, but serious complications are extremely rare.
