Continuing this tradition is its successor product ALEX2.

True or pollen-associated fruit allergy?

Calendar Icon 6/2/2021 Tag Icon TopNews, Alex, TrendsAndTopics, Services

Summer is calling - pollen-associated food allergy awaits many of us.

Molecular diagnosis is essential for the management and risk assessment of patients struggling with fruit allergy or pollen-related fruit allergy. The most important clinical task regarding fruit allergies is to identify the allergenic molecules and to screen out patients who are at high risk for systemic reactions.

Correct diagnosis of fruit allergies is not always easy and can be challenging. In fact, cross-reactive proteins can complicate the diagnosis of fruit allergy, as they can cause clinically irrelevant positive tests for cross-reactive foods. Therefore, molecular tests that include both cross-reactive components and primary food allergens are an important tool for precise diagnosis as well as dietary recommendations.
