Description

Order this Watermelon Serum test to measure the IgE antibody levels in a blood sample to detect a food sensitivity to watermelon. Watermelons are fruits from flowering vines belonging to the Cucurbitaceae (Gourd) family, with origins in southern Africa. Other plants in the Gourd family include cucumber, muskmelons, pumpkins, and squashes. Watermelons are a staple seasonal fruit harvested globally, especially in the southern United States. Watermelons contain several amounts of vitamins (A & C) and antioxidants. Due to their sweet and refreshing taste, watermelons are an essential ingredient in many food products, including:

  • Beverages
  • Frozen desserts (sorbet and popsicles)
  • Prepackaged fruit cups
  • Fruit salads
  • Yogurts
  • Alcoholic and non-alcoholic cocktails
  • Candies and desserts

A watermelon allergy is uncommon; however, individuals with hypersensitivity may experience an allergic reaction upon ingestion. The immune system views certain substances as harmful and produces IgE antibodies to combat these invaders. Unfortunately, these antibodies cause the release of a chemical called histamine, triggering the symptoms associated with an allergic reaction. The allergic reaction may happen minutes to a few hours after exposure to an allergen. The reaction may vary from mild to very severe and differ for everyone. An individual sensitive to watermelons may undergo the following symptoms:

  • Tingling sensation in or around the mouth
  • Swelling
  • Abdominal pain
  • Nausea or vomiting
  • Diarrhea
  • Itching, hives, or eczema
  • Congestion
  • Trouble breathing or wheezing
  • Lightheadedness

A severe, perhaps life-threatening allergic reaction known as anaphylaxis can occur in the most severe cases. An anaphylactic response requires immediate medical attention. Signs or symptoms of anaphylaxis include:

  • Rapid or increased pulse
  • Swollen throat or lump making it difficult to breathe
  • Low blood pressure
  • Extreme dizziness or loss of consciousness
