Cows Milk Protein Allergy Testing
Cows’ milk protein allergy (CMPA) occurs when the immune system reacts to proteins found in milk, such as casein and whey. This is different from lactose intolerance, which is a problem digesting lactose, the sugar in milk. In CMPA, the body views milk proteins as harmful, triggering an allergic response. Symptoms can range from mild, like hives or stomach issues, to severe reactions, such as difficulty breathing or even anaphylaxis.
This type of allergy is most commonly diagnosed in infants and young children, though it can affect people of any age. While many children outgrow the allergy by age 3 to 5, some may continue to experience symptoms into adulthood.

Symptoms of cows' milk protein allergy
Symptoms of CMPA can vary widely in type and severity and often occur shortly after consuming milk or dairy products. Common symptoms include:
- Skin reactions: Itching, hives (raised, red, itchy bumps), or eczema (itchy, red rash).
- Digestive issues: Nausea, vomiting, diarrhoea, and abdominal cramps.
- Respiratory problems: Runny nose, sneezing, coughing, wheezing, difficulty breathing, or throat tightness.
- Swelling: Swelling of the lips, tongue, face, or throat.
- Anaphylaxis: A life-threatening allergic reaction characterised by difficulty breathing, a drop in blood pressure, rapid pulse, and loss of consciousness. Anaphylaxis requires immediate medical attention.
If you suspect a milk allergy, it’s important to seek medical advice to receive a proper diagnosis and learn how to manage it effectively.
How we diagnose milk protein allergy
At OneMedicine, we use a combination of methods to diagnose CMPA:
- Medical history review: We’ll begin by asking detailed questions about your symptoms, their timing, and your diet. Keeping a food diary prior to your appointment can provide valuable insights.
- Blood tests: Blood tests can measure your immune system’s response to milk proteins by detecting specific IgE antibodies. This helps determine the likelihood of an allergy.

- Blood tests: Blood tests can measure your immune system’s response to milk proteins by detecting specific IgE antibodies. This helps determine the likelihood of an allergy.
- Elimination diet: If tests are inconclusive, we may suggest removing milk and dairy from your diet temporarily to monitor symptom changes. If symptoms improve and return once milk is reintroduced, it indicates a possible milk allergy.
How to manage cows' milk protein allergy
The main way to manage Cows’ Milk Protein Allergy (CMPA) is by avoiding all milk and dairy products. However, accidents can happen, so it’s important to be prepared. For those at risk of severe reactions, carrying an adrenaline auto-injector (EpiPen) is essential to treat anaphylaxis quickly. Mild symptoms like itching can be managed with antihistamines, but these should never replace adrenaline in serious cases.
Wearing a medical alert bracelet helps in emergencies, and careful label reading is key to avoiding hidden dairy in processed foods. There are many non-dairy alternatives available, like soy and almond milk, but be sure they aren’t cross-contaminated with milk during production.
Nutritional counselling can also help you find alternative sources of calcium and vitamin D, ensuring a balanced diet without dairy.
