The correct Answer is:
To determine the cause of an allergy, the following steps outline the process: 1. **Understanding Allergy**: An allergy is an overreaction of the immune system to substances that are usually harmless, such as pollen or dust. The immune system mistakenly identifies these substances as threats. 2. **Role of Allergens**: Allergens are the specific substances that trigger allergic reactions. Common allergens include pollen, dust mites, certain foods, and animal dander. 3. **Testing for Allergies**: To identify which allergens a patient is sensitive to, doctors perform allergy tests. This involves exposing the patient to small amounts of potential allergens. 4. **Injection of Pure Allergens**: In the allergy testing process, pure allergens are injected into the patient's body. This is done in a controlled environment to monitor the patient’s reaction. 5. **Observation of Reactions**: After the injection, the doctor observes the patient's reactions. If the patient is allergic to a specific substance, they will exhibit symptoms such as redness, swelling, or itching at the injection site. 6. **Conclusion**: Based on the reactions observed, the doctor can determine which specific allergens the patient is allergic to. Thus, the answer to the question is that **pure allergens** are injected into the patient's body for determining the cause of allergy.
