About the test
This test measures the body's allergic reaction to cochineal extract, a natural red dye made from the Dactylopius coccus insect. People might be exposed to this allergen through certain foods, drinks, or at work. The test checks for specific IgE antibodies that indicate an allergic response to cochineal extract. It's a helpful tool for providers to diagnose allergies, used alongside other clinical information.
Who might need this test? It's also a good option for those who can't undergo skin allergy tests due to skin conditions, recent medication use, uncooperativeness, or a high risk of severe allergic reactions. Providers might suggest this test if you have symptoms of an allergy, such as:
- Itchy skin or hives
- Swelling
- Difficulty breathing
- Stomach pain or vomiting after eating certain foods
Understanding Your Results
A positive result means you have IgE antibodies against cochineal extract, indicating a possible allergy. However, not everyone with positive results will have symptoms when exposed to the allergen. Diagnosing a food allergy is complex and should include a thorough evaluation by a healthcare provider. Remember, not all food sensitivities involve IgE antibodies, so further testing might be needed.
Sample Required?
Yes, 0.3 mL of serum is needed for this test.
