Cow's Milk Components Allergy Blood Test
Milk and Milk Proteins Allergy Blood Test
Milk allergy is an autoimmune response to milk proteins, such as casein (found in the curd) and whey (found in the liquid part of the milk). Cow’s milk allergy (CMA) is the most common type; however, some people get symptoms from sheep or goats’ products, as well.
Milk allergies are most common in young children and may become less severe over time. Symptoms range from a mild rash or digestive discomfort to wheezing or full anaphylaxis.
Managing an allergy may include using certain replacement products such as hypoallergenic formulas or soy milk, as well as supplements to replace calcium in your child’s diet.
If you think your child may be experiencing an allergy to milk proteins, it is important to consult with your Midland Health GP. We offer same-day GP appointments and we’re here to help, advise and offer guidance for you and your family.
Milk allergy is an immune condition that causes an allergic reaction when even the smallest amount of milk is consumed. It can be a potentially life-threatening condition, especially if it causes anaphylaxis.
Lactose intolerance or the intolerance of milk proteins can have unpleasant effects, such as digestive problems, excessive wind, bloating, diarrhoea and abdominal cramps but it is not a life-threatening condition. Therefore, it is extremely important to get the right diagnosis.
If you suspect your child may have an allergy to dairy products, you should book an appointment with a GP immediately to discuss their symptoms and do the necessary tests to confirm whether they have a milk protein allergy or not.
Milk allergy can have many symptoms, some of which occur immediately and some - a few hours after the consumption of products that contain milk. This depends on the type of allergic reaction.
If your child has a Non-IgE mediated food allergy (the most common type), symptoms develop within 72 hours of consuming milk proteins and may include:
If your child’s allergy is found to be IgE mediated, it can have immediate effects, such as:
Anaphylaxis is the most severe form of allergic reaction. It is a life-threatening medical emergency that develops within minutes of consuming milk-containing products (or other products you are allergic to).
During anaphylaxis, swelling narrows the airways and can cause an inability to breathe. Some of the early signs to look out for include:
Anaphylaxis is treated with adrenaline administered as an epinephrine shot, usually using an EpiPen or a similar device. Even when the treatment has alleviated the symptoms, you should still go to the emergency room and get examined by a doctor.
During your appointment with your Midland Health GP, your doctor will ask you about the symptoms that you have spotted and will perform a physical exam. At this stage, it is helpful to present your doctor with a food diary, detailing the food your child has consumed over the previous two weeks and the possible milk allergy symptoms you have noted.
To confirm the milk allergy diagnosis, we can do two types of allergy tests:
Sometimes, both tests may be required to confidently confirm or reject the diagnosis. An additional method to use could be the oral test challenge where the patient is asked to consume increasing amounts of milk to see whether there is a reaction and what the threshold is.
If your doctor thinks that something else may be causing the symptoms, they may refer you for further testing at the Midland Health clinic.
If a milk allergy diagnosis is confirmed, the only way to treat it is to remove products that contain milk proteins from your child’s diet. If your baby has a cow’s milk allergy, you could be offered hydrolysed milk as an alternative; it’s a special type of milk formula that’s safe for babies who are allergic to milk.
If your child has been diagnosed with a milk allergy, you should avoid all dairy products, including:
Not all products that contain dairy are as easy to spot. This is why you should read the labels very carefully and avoid anything that contains:
Cow’s milk allergy (CMA) is the most common type of milk allergy. It is an immune reaction to one or more of the proteins contained in milk. It is most commonly diagnosed in babies under 1.
We can use a blood test or a skin prick test, or a combination of both to check for a milk allergy.
If you experience an allergic reaction within 72 hours of consuming dairy products, you may be allergic to milk. If you think that might be the case, book an appointment with one of our GPs to discuss your symptoms.
Milk allergy is mostly diagnosed in small children and babies. The majority of children grow out of their milk allergy. However, some people don’t and continue to have milk allergy symptoms into adulthood.
It is highly unlikely that you will develop a milk allergy as an adult. However, it is common to develop lactose intolerance later in life and the two could be confused as they could be triggered by the same products.
