Tapeworm (Echinococcus) IgG Antibody Test in Oregon

The tapeworm (Echinococcus) IgG antibody test checks your blood for antibodies your immune system makes against Echinococcus tapeworm infection. It is ordered when a doctor suspects exposure from contaminated food, water, or contact with infected animals, or to help evaluate a cyst found on imaging.

What it measures

Echinococcus IgG antibodies — Proteins your immune system produces in response to Echinococcus tapeworm infection.
Antibody level (titer) — A measure of how much antibody is present; higher levels may suggest active infection.
Species-specific antibodies — Some tests distinguish between Echinococcus species, which can help guide care.

Who it is for

Doctors typically order this test for people with symptoms or imaging findings that suggest echinococcosis, or those with a history of travel to or residence in areas where the parasite is common.

Preparation

No fasting or special preparation is needed. Tell your doctor about any medications you take, as some can affect antibody test results.

Results and what they mean

Results are reported as positive, negative, or equivocal, sometimes with a numeric titer. A positive result does not confirm active infection, and a negative result does not rule it out. Only a clinician can interpret your results in the context of your history, symptoms, and other tests. This is general information, not medical advice.

Frequently asked questions

How is the test done?

A blood sample is drawn from a vein in your arm, usually in a clinic or lab. The sample is then sent to a laboratory for analysis.

How long do results take?

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

Can I get this test without a doctor's order?

Some labs offer it directly, but it is best ordered and interpreted by a clinician who knows your health history.

What if my result is positive?

A positive result means antibodies were found. Your doctor will consider your symptoms, imaging, and other tests to determine if you have an active infection and what steps to take next.
