Allergen, Individual-Food Grapefruit Citrus paradisi F33

The Allergen, Individual-Food Grapefruit Citrus Paradisi F33 is a home-based allergen test that detects grapefruit-specific IgE antibodies using a small capillary (finger‑prick) blood sample, analysed by an accredited laboratory. The test provides a quantitative result (expressed in kU/L with an IgE class) to help determine sensitization to grapefruit (Citrus paradisi) and guide safe dietary choices for residents in Dubai and across the UAE.

This test is useful for individuals who experience immediate reactions such as oral itching, hives, angioedema, or more severe responses after consuming grapefruit or products containing grapefruit. It offers the convenience of at-home sample collection with laboratory-grade accuracy and clinician-friendly reporting; positive or clinically significant results should be reviewed with an allergist or physician for confirmation, possible oral challenge, and a personalised management plan consistent with UAE healthcare standards.
