Ascaris (Common Roundworm) Allergy Test in Idaho

The Ascaris allergy test is a blood test that looks for specific IgE antibodies, the immune proteins linked to allergic reactions, against Ascaris lumbricoides, the common roundworm. It is usually ordered when a clinician suspects that allergy-like symptoms such as wheezing, itchy skin, or digestive upset may be connected to this parasite rather than to a more typical allergen.

What it measures

Ascaris-specific IgE — The main marker; shows whether your immune system has made antibodies that react to Ascaris proteins.
Total IgE — A general allergy antibody level that can be elevated by many allergic and parasitic conditions.
Eosinophil-related context — Sometimes reviewed alongside this test because eosinophils are immune cells often raised in parasite-related reactions.
Other allergen-specific IgE — May be tested together to help separate a true Ascaris reaction from reactions to foods, pollen, or dust mites.

Who it is for

A doctor, allergist, or infectious disease specialist typically orders this test when symptoms and exposure history suggest a possible Ascaris-related allergic response. It may also be used to help evaluate unexplained high eosinophil counts or allergy symptoms that do not fit common triggers.

Preparation

No fasting or special preparation is needed for this blood test. Tell your clinician about any medications you take, since some drugs can affect immune test results.

Results and what they mean

Results are reported as a numeric level of Ascaris-specific IgE, often with a reference range or a class score from negative to strongly positive. A single result does not confirm or rule out an infection or allergy on its own; a clinician interprets it with your symptoms, exposure history, and other tests. This is general information only and is not medical advice.

Frequently asked questions

Does a positive result mean I have roundworms?

Not necessarily. A positive IgE result shows immune sensitization to Ascaris proteins, which can happen with past or current exposure. A clinician may order stool tests or other evaluations to check for an active infection.

Can this test tell the difference between allergy and infection?

No. It measures an immune antibody response that can occur with either. Your clinician combines the result with your history and other tests to understand what is going on.

Do I need to fast before this test?

No. Fasting is not required, and you can take the test at any time of day unless your clinician gives different instructions.

How long do results take?

Results are typically available within 1 to 3 business days, though timing can vary by laboratory.
