IgE Immunoassay for Common Allergens (Screening Mix)
This blood test measures levels of Immunoglobulin E (IgE), a protein involved in allergic reactions, to screen for sensitivities to common allergens.
["Helps identify potential allergies to foods, environmental triggers, or other substances."]

What This Test Measures
IgE antibodies are part of your immune system’s response to allergens like pollen, dust mites, pet dander, certain foods, or insect stings. This test detects specific IgE antibodies against a mix of common allergens, helping determine if you may react to them.
Why It’s Done
Your doctor may recommend this test if you experience symptoms like sneezing, itching, hives, or difficulty breathing after exposure to potential allergens. It’s often used as part of an allergy screening or diagnosis.
Sample Collection
A small blood sample is drawn from your arm. The test uses a simple blood draw, similar to other routine blood tests. No special preparation is needed, but fasting may be advised depending on your doctor’s instructions.
What to Expect After Testing
Results are typically available within a few days. If positive, further testing (like skin prick tests or allergy challenges) may be needed to pinpoint specific allergens. Follow-up with your healthcare provider to discuss next steps.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions
This test helps identify if your immune system is reacting to specific allergens, which can guide treatment options such as allergy medications, avoidance strategies, or immunotherapy. High IgE levels may indicate an allergic predisposition but don’t confirm a diagnosis alone.
A positive result suggests your body may produce IgE antibodies in response to certain allergens, increasing the likelihood of allergic reactions. It doesn’t confirm a diagnosis but may prompt further evaluation by an allergist.
No specific dietary restrictions apply, but always follow your doctor’s instructions. If fasting is required for other tests, note it here.
