Diagnosis
Identifying anaphylaxis is crucial for understanding the cause of the reaction and preventing future occurrences. Diagnosis is primarily based on the symptoms exhibited by the individual. Allergists employ two main methods for testing specific allergens: skin tests and blood tests.
In a skin test, the suspected allergen is applied in small quantities to the skin to observe any reaction. On the other hand, a blood test confirms anaphylaxis by measuring the levels of tryptase, an enzyme released during an allergic reaction. However, for an accurate diagnosis, the blood test must be conducted within a few hours after the event.
Common Triggers
When it comes to anaphylaxis, there are several common triggers that can cause a severe allergic reaction. While everyone has different IgE antibodies, certain allergens tend to lead to anaphylaxis in a large number of people. The most prevalent trigger is food allergies, with peanuts being the top culprit. In fact, peanut allergies account for 45 percent of all food allergies that result in anaphylaxis. Following closely behind are tree nuts and seeds, which contribute to 19 percent of anaphylactic reactions, and milk, which is responsible for 10 percent of cases.
In addition to food allergies, other triggers include reactions to drugs, blood products, latex, and insect stings. These triggers are relatively common and can also lead to anaphylaxis in susceptible individuals.
