When is a test for cow’s milk allergy useful?

A test for cow’s milk allergy is useful if symptoms occur after consuming milk or milk products. These symptoms can range from mild skin rashes to severe digestive and respiratory problems. Testing is especially important in babies, young children and adults with unexplained allergic reactions.

Complaints indicating cow’s milk allergy

Cow’s milk allergy can cause several symptoms. If you or your child suffers from the symptoms below after consuming milk, a test is recommended:

• Skin rash, eczema or itching
• Diarrhoea, vomiting or abdominal pain
• Colicky cramps in babies
• Bloated belly or flatulence
• Shortness of breath, wheezing or coughing
• Runny or stuffy nose with no obvious cause

These symptoms can occur immediately after eating or drinking milk, or they can occur hours later.

When should you consider a cow’s milk allergy test?

In babies and young children

A test is especially useful if a baby or young child regularly suffers from intestinal cramps, skin rashes or breathing problems. Cow’s milk allergy is most common in the first years of life and is often confused with lactose intolerance or other digestive problems.

In adults with recurrent complaints

Although cow’s milk allergy is less common in adults, it can still develop. A test can provide clarity if someone is experiencing digestive problems, skin reactions or respiratory symptoms with no obvious cause.

With family history of allergies

People with a family history of allergies, such as hay fever, eczema or asthma, have an increased risk of cow’s milk allergy. In this case, testing is extra relevant, especially in children.

In case of persistent symptoms despite an elimination diet

Some people avoid dairy products in their diet but continue to have symptoms. A test can help determine whether there really is an allergy, or whether another cause is causing the symptoms.

Which test is suitable to diagnose cow’s milk allergy?

There are several ways to test for cow’s milk allergy. A blood test, such as the cow’s milk allergy self-test, measures the presence of IgE antibodies against milk proteins. This is a quick and reliable method that can be performed at home.

Other test methods are:

• Skin prick test at allergist
• Elimination provocation test under the supervision of a doctor

For an initial indication, a self-test is a good option. In case of a positive result, it is recommended to consult a doctor for further diagnostics.

Conclusion

A test for cow’s milk allergy is useful for recurrent skin, intestinal or respiratory symptoms after milk consumption. This is especially true for babies, young children and adults with persistent allergic symptoms. Even if milk products are avoided but symptoms persist, a test can help determine the cause. A cow’s milk allergy self-test offers a quick initial indication, after which further medical diagnosis may be needed if the result is positive.
