Allergen, Individual-Food Oyster Ostrea edulis F290

The Allergen, Individual‑Food Oyster (Ostrea edulis) F290 is a home collection test that measures specific IgE antibodies to oyster (Ostrea edulis) using a small capillary blood sample. The sample is analyzed by laboratory immunoassay to provide a quantitative sIgE result (reported in kU/L and as an IgE class), which helps distinguish IgE‑mediated oyster allergy from non‑allergic food intolerance and informs safe dietary decisions.

This test is suitable for individuals in Dubai who suspect an allergic reaction to oysters or who need objective confirmation before food reintroduction or specialist referral. Results are delivered digitally for convenient review and can support clinicians in advising avoidance, challenge testing, or further allergy workup; note that clinical history and, when appropriate, supervised oral food challenges remain essential for definitive diagnosis and management of food allergy.
