This Blackberry Allergy test measures the IgE antibody levels in a blood sample to detect a food sensitivity to blackberries. Blackberries are a fruit of the Rosaceae (Rose) family with origins in Britain. Blackberries are a popular fruit grown globally in countries like Mexico and Chile. Other fruits in the rose family include apples, pears, strawberries, cherries, peaches, plums, raspberries, and prunes. Blackberries contain many vitamins (K & C), antioxidants, and minerals (Manganese) and are high in fiber. Blackberries also help protect against inflammation and reduce the risks of diabetes and cancer. Due to its many health benefits, blackberries are an essential ingredient in many products, including:
- Jams, preserves, purees
- Beverages (smoothies and juices)
- Frozen desserts
- Herbal teas
- Salads
- Yogurts
- Marinades, sauces, and dressings
- Alcoholic and non-alcoholic cocktails
- Candies and desserts
- Wine
While an allergy to blackberries is uncommon, it may cause a reaction in individuals with food sensitivity. In addition, ingesting blackberries or blackberries-based products may activate an individual's immune system response. The immune system views certain substances as harmful and produces IgE antibodies to combat these invaders. Unfortunately, these antibodies cause a chemical called histamine to be released in the blood, which prompts an allergic reaction.
An allergic reaction may vary from mild or moderate to severe and differ for each individual. An individual may experience allergic reaction minutes to a few hours after exposure to an allergen. An individual allergic to blackberries may experience 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
An extreme, potentially 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 may include:
- Rapid or increased pulse
- Swollen throat or lump making it difficult to breathe
- Low blood pressure
- Extreme dizziness or loss of consciousness
