Lemon F208

At IntroLab in Belgrade, we provide the lemon F208 IgE test, designed to diagnose allergies to lemons and other citrus fruits. If you’re experiencing symptoms or suspect an allergy, this test is a great choice for you.

What is the lemon F208 test?

The lemon F208 test targets a specific food allergen. It plays an important role in diagnosing allergic reactions to lemons and other citrus fruits by detecting the presence of specific immunoglobulin E (IgE) antibodies in the blood, which signal an allergic response.

When is the test performed?

The lemon F208 IgE test is usually conducted when there is a suspicion of an allergic reaction to lemon or other citrus fruits. This may include:

• Symptom onset: If a person develops allergy symptoms after consuming lemon.
• Allergy history: If the person has a known history of food or other allergies.
• Prior to immunotherapy: To confirm sensitization before starting immunotherapy.
• Doctor’s recommendation: A doctor may suggest this test based on the clinical picture and symptoms.

Symptoms of lemon allergy

Lemon allergy symptoms can vary from mild to severe and may include:

• Skin rash: Redness, itching, or rash on the skin.
• Digestive symptoms: Nausea, vomiting, or diarrhea after consuming lemon.
• Respiratory symptoms: Coughing, sneezing, difficulty breathing, or a feeling of tightness in the throat.
• Eyes and nose: Red, watery eyes, and a runny nose.
• Anaphylactic reaction: In rare cases, a severe anaphylactic reaction may occur, requiring urgent medical attention.

Why does a lemon allergy occur?

A lemon allergy, like other food allergies, happens when the immune system mistakenly identifies proteins in lemons as harmful. Here are a few reasons why this may happen:

• Immune system sensitivity: The immune system produces immunoglobulin E (IgE) antibodies in response to lemon proteins, which trigger the release of chemicals like histamine, causing allergic symptoms.
• Genetic factors: Individuals with a family history of allergies are more likely to develop allergies, including those to lemons.
• Frequent exposure: Repeated exposure to lemons can sometimes increase the risk of developing an allergy.
• Cross-reactivity: Those allergic to certain types of pollen, such as birch, may also react to lemons due to similar protein structures.
• Gut health: Some researchers believe that an imbalance in gut microbiota can influence the immune system and increase the likelihood of developing allergies.

If you suspect you have a lemon allergy, it’s important to consult a doctor for diagnostic testing and advice on managing the symptoms.
