Lactose Intolerance Test

Lactose Intolerance Test

We provide hydrogen breath testing for lactose intolerance, which specifically examines the body’s reaction to certain milk proteins such as:

• Alpha-lactalbumin – a milk protein
• Beta-lactoglobulin – a milk protein
• Casein – a milk protein
• Cow’s milk, goat’s milk, sheep’s milk
• Whey

Causes of Lactose Intolerance

Lactose intolerance arises when the small intestine fails to produce sufficient lactase, an enzyme responsible for breaking down lactose (the natural sugar found in milk). Lactase converts lactose into simpler sugars, like glucose, that the body can easily absorb.

When lactase levels are not enough, consuming milk and dairy products with lactose can trigger uncomfortable digestive symptoms like painful gas, diarrhea, and bloating. Undigested lactose can also promote the growth of harmful bacteria in the gut since these bacteria feed on the remaining lactose.

When Should You Consider Lactose Intolerance Testing?

You should consider getting tested if you experience symptoms commonly associated with lactose intolerance, such as:

• Digestive discomfort after taking milk or dairy products
• Bloating, gas, or diarrhea following dairy consumption
• Nausea and vomiting

Your doctor may also recommend this test to confirm or rule out a diagnosis of lactose intolerance. The test can be conducted at any time.

Key Considerations for Intolerance Testing

When it comes to intolerance testing, it’s essential to approach the process with caution. Not all tests available online are scientifically certified or reliable, and interpreting the results can be challenging, often leading to false positives or negatives.

Here are some important factors to keep in mind when evaluating intolerance tests:

• Scientific validation: Opt for tests that have been rigorously tested and scientifically validated. Evidence-based approaches available in reliable scientific journals are usually more dependable.
• Laboratory accreditation: Consider tests from accredited laboratories that adhere to recognized quality standards. Accreditation ensures greater reliability in the results.
• Scope of analysis: Certain tests claim to offer complete analyses of potential intolerances like environmental triggers, food, and other sensitivities. However, it’s important to note that current knowledge supports comprehensive testing primarily for allergies, not intolerances.
• Professional guidance: Always seek advice from a qualified healthcare provider, like a registered dietitian or an allergy specialist, before and after testing. Professional guidance ensures that the test results are interpreted accurately and that any recommended management plans are relevant to your specific symptoms. Be cautious of services that promise result interpretations without a detailed medical history, as these may lack accuracy and relevance.
• Rate and accessibility: Evaluate the charges and accessibility of the test, including any added fees for result interpretation or follow-ups. Avoid inexpensive, all-encompassing tests, as they may lack credibility and not provide valuable insights.

Lastly, bear in mind that intolerance testing is only a single part of the diagnostic process. A detailed physical examination, medical history review, and possibly additional diagnostic tests are essential for identifying and managing the root causes of your symptoms. Collaborating with your GP and taking a multidisciplinary approach can help ensure effective symptom management and long-term well-being.
