Serum Immunoglobulin (Ig) Profile with Allergen-Specific Testing (Screening Mix)
This test measures your body’s immune response to common allergens, including common airborne allergens, foods, and environmental triggers. It helps identify whether your immune system is reacting to specific substances.
["This screening helps determine if allergens may be causing your symptoms and guides allergy treatment options."]

What Does This Test Measure?
The test includes measurements of total serum immunoglobulin levels (IgE, IgG, IgA, IgM) and specific IgE antibodies against a mix of common allergens. IgE is particularly important because it’s linked to allergic reactions. The mix typically includes allergens like pollen, dust mites, pet dander, mold, certain foods, and insect venom.
Why Might You Need This Test?
Your healthcare provider may recommend this test if you have symptoms like sneezing, itching, rash, hives, swelling, difficulty breathing, or digestive issues that suggest an allergic reaction. It’s also used to evaluate suspected food allergies, environmental allergies, or reactions to insect stings.
How Is the Test Performed?
A blood sample is taken from a vein in your arm. The sample is sent to a lab where it’s analyzed using immunoassay methods to detect specific IgE antibodies against the allergens in the mix. Results are reported as positive or negative for each allergen, indicating whether your immune system is sensitized to them.
What Do My Results Mean?
Positive results for specific allergens mean your immune system has detected those substances and may produce symptoms when exposed. However, a positive test alone doesn’t confirm an allergy—it only indicates sensitization. Further evaluation, such as skin prick tests or additional blood tests, may be needed to confirm an allergy and guide treatment.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Clinical Significance: This test helps identify potential allergens driving symptoms, allowing for targeted allergy avoidance, immunotherapy (like allergy shots), or other treatments. It’s particularly useful for diagnosing conditions like hay fever, food allergies, or allergic asthma. However, results should always be interpreted by a healthcare provider in the context of your symptoms and medical history.
