What is the purpose of this test?
Order this Peach Allergy IgE Blood Test, which measures the IgE antibody levels in the blood to detect an allergy to peaches. The peach fruit, from trees in the Prunus genus of the Rosaceae family, is highly sought-after worldwide. However, some peach-sensitive individuals may experience allergic reactions such as oral allergy syndrome, hives, or anaphylaxis. Those sensitive to the protein Pru p 1 tend to experience milder symptoms than those sensitive to Pru p 3 or Pru p 7. While pasteurized forms of peach can be consumed by those sensitive to heat-labile Pru p 1, this is not an option for those sensitive to heat-stable proteins like Pru p 3. Additionally, there is a risk of cross-reactivity between specific peach proteins and other fruits like cherry, plum, apricot, orange, or pomegranate. Severe fruit-induced allergies may be linked to cypress pollen, with Pru p 7 being a marker for these reactions.
When should I order a Peach Allergy IgE Blood Test?
Individuals may order this Peach Allergy Blood Test if they have experienced symptoms related to a peach allergy. Allergy symptoms vary depending on the individual, ranging from mild to severe reactions. Most food-related symptoms occur within two hours of ingestion but frequently begin within minutes. In addition, the response can be delayed by four to six hours or even longer in some rare cases.
An allergic reaction may affect the skin, intestinal lining, and air pathways. Individuals with a peach allergy may experience one or more of the following symptoms:
- Tingling sensation near or around the mouth
- Abdominal discomfort
- Nausea or vomiting
- Itching or hives
- Difficulty breathing, swallowing, or wheezing
In some cases, a severe, possibly life-threatening allergic reaction known as anaphylaxis may occur. An anaphylactic response requires immediate medical attention. Signs or symptoms of anaphylaxis may include:
- Rapid or increased heart rate
- Swollen throat or lump making it difficult to breathe
- Low blood pressure
- Extreme dizziness or loss of consciousness
