Egg White F1

Among food allergies, an allergy to egg whites is one of the most common, particularly in children. This allergy can trigger a range of symptoms, from mild to very severe. To address this, IntroLab in Belgrade offers the Egg White F1 test, specifically designed to detect the presence of IgE antibodies that react to the proteins in egg whites.

Why is it important to take the Egg White F1 test?

An allergy to egg white can present in different ways. Symptoms can be mild, such as rashes or itching, but they can also be severe, such as life-threatening anaphylactic shock. This test helps identify the allergens responsible for allergic and anaphylactic reactions. It is also used to confirm sensitization before beginning immunotherapy.

How is the test performed?

The test requires a blood sample, and the process of drawing blood is quick and simple. The laboratory then analyzes the sample to detect the presence of specific IgE antibodies that react to egg white. If the levels of these antibodies exceed a certain threshold, it could indicate the presence of an allergy.

Which components of egg white can trigger an allergic reaction?

The two primary components of egg white commonly linked to allergic reactions are:

• Ovomucoid (Gal d 1)
• Ovalbumin (Gal d 2)

Ovomucoid is the dominant allergen in egg white and is very heat-stable. High levels of specific IgE antibodies to ovomucoid may indicate a persistent egg allergy. In contrast, ovalbumin is the most abundant protein in egg white, but it denatures easily when exposed to heat.

Who is this test for?

This test is especially helpful for parents of young children who display symptoms of an egg allergy. It is also useful for individuals who have experienced allergic reactions after consuming eggs or products containing eggs.

An egg white allergy can be difficult to manage, but with proper diagnosis and treatment, it’s possible to control symptoms and prevent severe reactions. If you suspect you have an egg white allergy or want more information about the Egg White F1 test, visit IntroLab in Belgrade.
