Understand How Your Body Handles Dairy
Bloating, cramps, or rushing to the bathroom after having milk or cheese? If dairy leaves you feeling worse than it should, lactose intolerance may be the underlying cause. This common digestive condition occurs when your body lacks lactase, the enzyme required to break down lactose, the sugar found in dairy.
The GetTested Lactose Intolerance Test offers a comprehensive approach to identifying both hereditary and temporary lactose intolerance, combining breath analysis with DNA testing for accurate, science-backed results.
What Does the Test Measure?
Breath Test – Measures levels of hydrogen and methane gas over 3 hours after consuming a lactose solution. Elevated gas levels indicate poor lactose digestion.
DNA Test – Analyses your genetics to identify whether you carry a hereditary lactase deficiency.
This dual-testing method allows you to detect both primary (genetic) and secondary (temporary or condition-related) lactose intolerance.
Common Symptoms of Lactose Intolerance
If your body struggles to digest lactose, symptoms typically appear within a few hours of consuming dairy and may include:
Abdominal pain or cramping
Bloating and gas
Diarrhoea
Nausea
Flatulence
Symptoms vary depending on the level of lactase deficiency and the amount of dairy consumed.
Types of Lactose Intolerance
Understanding the type of intolerance you have can guide better decisions about your diet and long-term digestive health:
Primary Lactose Intolerance – A genetic condition where lactase production declines with age. Common in people of Asian, African, and Southern European descent.
Secondary Lactose Intolerance – Caused by gut damage from conditions like Crohn’s disease, coeliac disease, or gastroenteritis. Usually temporary.
Congenital Lactose Intolerance – A rare, lifelong condition present from birth, where the body produces no lactase enzyme.
Lactose Intolerance vs. Milk Allergy
It's important to distinguish between lactose intolerance and a cow’s milk allergy:
Lactose intolerance is a digestive issue—caused by enzyme deficiency—not an immune reaction.
Milk allergy involves the immune system reacting to milk proteins, often causing more severe symptoms like hives, swelling, or breathing problems.
If you’re unsure, testing is the safest and most accurate way to determine what’s causing your symptoms.
How the Test Works
This at-home kit is designed for ease and accuracy:
Breath Test – You’ll collect multiple breath samples over three hours after drinking a lactose solution, using provided glass tubes.
DNA Test – A simple swab is included to collect your DNA for genetic analysis.
Lab Analysis – Your samples are analysed in a certified lab.
Digital Results – Receive your personalised report within 10–15 business days, showing whether your symptoms are linked to lactose intolerance—and which type.
Next Steps for Gut Support
If you test positive for lactose intolerance, consider:
Reducing or avoiding lactose-containing foods
Exploring lactose-free dairy alternatives
Supporting gut healing (if your intolerance is secondary)
Supplementing with lactase enzymes if needed for occasional dairy consumption
