Total Serum Immunoglobulin E (IgE) with Allergen-Specific IgE Profile (Screening Mix)
This test measures your body’s immune response to common allergens, including common airborne allergens, foods, and insect venom. It helps identify specific triggers for allergic reactions.

What This Test Measures
The test includes a general measurement of total IgE levels in your serum and specific IgE antibodies against a mix of common allergens. IgE is a type of antibody your immune system produces in response to allergens, which can cause allergic reactions like sneezing, itching, or skin rashes.
How the Test Works
Blood is drawn and processed to separate serum, which is then analyzed using immunoassay methods (likely fluorescence or chemiluminescence) to detect IgE levels and specific IgE responses to the included allergens. This helps pinpoint which allergens may be causing your symptoms.
Why It’s Done
Your healthcare provider may recommend this test if you have symptoms like sneezing, itching, skin reactions, or respiratory issues that suggest allergies. It’s also used to confirm allergies suspected through history or physical exam before planning treatment.
What to Expect Before the Test
No special preparation is needed. You may have a small needle inserted into your arm to draw blood, which usually takes a few minutes. Wear comfortable clothing and bring any medications you’re currently taking.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Elevated total IgE levels or specific IgE responses to allergens can indicate an allergic reaction risk. While these results don’t confirm a diagnosis alone, they help guide further testing or treatment plans, such as allergy shots or avoiding specific allergens. Results may also be used to monitor response to allergy management strategies.
