Allergen, Individual-Food Lemon Nimbu (Citrus Limon) F33

The Allergen, Individual-Food Lemon Nimbu (Citrus Limon) F33 test is a targeted at‑home diagnostic designed to detect sensitisation to lemon (Citrus limon). It measures specific IgE antibodies against lemon proteins from a small blood sample, using laboratory immunoassay methods to determine whether the immune system has produced an allergic response to this specific citrus allergen.

This test is important for people in Dubai who experience reactions after consuming or handling lemons — such as hives, oral itching, swelling, gastrointestinal upset, or respiratory symptoms — and want objective evidence to guide dietary choices. Results help clinicians and dietitians advise on avoidance strategies, risk of cross-reactivity with other citrus fruits, and whether further evaluation by an allergist (e.g., supervised challenge or skin testing) is recommended.
