Causes and Risk Factors of Class 2 Egg White Allergy
Class 2 egg white allergy is caused by specific proteins found in egg whites, such as ovalbumin and ovomucoid. These proteins, known as allergens, trigger an immune response in individuals who are sensitive to them. When someone with an egg white allergy consumes or comes into contact with egg whites, their immune system recognizes these proteins as harmful and releases chemicals, such as histamines, leading to allergic symptoms.
Children are more likely than adults to have egg allergies, and many children outgrow them before reaching adolescence. Risk factors for egg allergy include having atopic dermatitis (eczema), a condition that makes the skin more susceptible to allergens, and having a family history of allergies. If one or both parents have allergies, their children are more likely to develop allergies as well, including egg allergies.
The symptoms of class 2 egg white allergy can vary from mild to severe. Common symptoms include skin inflammation, hives, nasal congestion, digestive issues (such as stomach pain, nausea, or diarrhea), and asthma. In some cases, individuals may experience anaphylaxis, a severe and potentially life-threatening reaction that can cause difficulty breathing, a drop in blood pressure, and loss of consciousness. Prompt medical attention is essential if anaphylaxis occurs.
To prevent allergic reactions, individuals with egg white allergies should carefully read food labels to identify any potential egg-containing ingredients. When eating out, it’s important to inform restaurant staff about the allergy to avoid cross-contamination. Wearing an allergy bracelet or necklace can also help emergency responders quickly identify the allergy in case of an accidental exposure. Additionally, informing caregivers, such as teachers or daycare providers, about the allergy is crucial to ensure proper care and supervision.
Egg white exposures can occur in various foods and products, so it’s important to be cautious. Some unexpected sources of egg whites include marshmallows, mayonnaise, certain baked goods, and pasta. Cross-contamination can also happen when using utensils or cookware that has come into contact with egg whites. Thoroughly cleaning kitchen surfaces and avoiding shared equipment can help prevent exposure.

Symptoms of Class 2 Egg White Allergy
Symptoms of class 2 egg white allergy can range from mild skin reactions to severe respiratory issues. When someone with an egg allergy consumes egg whites or products containing egg whites, their immune system overreacts to the proteins in the eggs, triggering an allergic response. The symptoms can vary from person to person and may occur within minutes or hours after exposure. Common symptoms include:
- Skin reactions: This can include hives, itching, redness, or swelling on the skin.
- Nasal congestion: Some individuals may experience a runny or stuffy nose, sneezing, or sinus pressure.
- Respiratory issues: Allergic reactions to egg whites can cause wheezing, coughing, shortness of breath, or even asthma attacks in some cases.
- Digestive symptoms: Symptoms such as nausea, vomiting, abdominal pain, diarrhea, or cramping may occur.
In severe cases, anaphylaxis can occur, which is a severe and potentially life-threatening allergic reaction. Symptoms of anaphylaxis include difficulty breathing, tightness in the throat, rapid pulse, dizziness, and loss of consciousness. If someone experiences these symptoms, it is essential to seek immediate medical attention.
It’s important to note that these symptoms may not be exclusive to egg white allergy and can also occur with other types of food allergies. If you suspect an egg allergy, it’s best to consult with an allergist for a proper diagnosis and to develop an appropriate management plan.
| Allergy Symptoms | Description |
|---|---|
| Skin Reactions | Hives, itching, redness, swelling on the skin |

Diagnosing Class 2 Egg White Allergy
If you suspect a class 2 egg white allergy, a healthcare professional can perform diagnostic tests to confirm the allergy. These tests are essential to determine the appropriate management and treatment plan for individuals with egg allergies. Here are some common diagnostic methods for diagnosing class 2 egg white allergy:
Skin-Prick Tests:
During a skin-prick test, a small amount of egg white extract is placed on the skin, usually on the forearm or back. The skin is then pricked with a tiny needle to allow the allergen to enter the skin. If a raised, red bump surrounded by a white wheal appears, it indicates a positive reaction to the allergen. This test helps identify if the individual is sensitized to egg proteins, but it does not confirm the severity of the allergy.
Blood Tests:
Blood tests, such as the specific IgE blood test, can measure the levels of antibodies produced in response to egg proteins. This test can help determine the likelihood of an allergic reaction to egg whites. Results are typically reported as a numerical value or class, indicating the severity of the allergy.
Oral Food Challenges:
An oral food challenge is performed under medical supervision, where small amounts of egg white are consumed gradually to monitor any allergic reaction. This test can help confirm or rule out an egg white allergy and assess the tolerance level to egg proteins.
Food Elimination Diets:
In some cases, a healthcare professional may recommend an elimination diet, where all foods containing egg whites are removed from the individual’s diet for a specific period. If symptoms improve during this elimination period and return when egg whites are reintroduced, it suggests an egg white allergy.
It’s important to consult with a healthcare professional to determine the most appropriate diagnostic test based on individual circumstances. These tests, along with a detailed medical history and symptom evaluation, can help accurately diagnose class 2 egg white allergy and guide appropriate management strategies.
