How to prepare
- Food. You usually do not need to fast strictly, but it is better to come 3 to 4 hours after a light, non-fatty meal. Check with the lab.
- Medicines. Do not stop anything on your own. Tell your doctor what you take. They will decide if anything needs to change before the test.
- Clothing. A sleeve you can easily roll up above the elbow.
What to bring
- Your referral or list of tests

How it goes
- You sit down and rest your arm on the armrest
- A band is tied above your elbow, and you are asked to clench your fist a few times
- The skin is wiped with antiseptic
- A quick prick. Blood fills the tubes in a few seconds
- The needle comes out, and a cotton pad is pressed on the spot
What you'll feel
- A quick prick, like a pinch
- Sometimes slight dizziness. Tell the nurse, and they will help you lie down
Afterwards

Common questions
How do people get echinococcus?
From the parasite's eggs: from dogs, unwashed hands, vegetables, and berries.
If no antibodies were found, is there definitely no cyst?
Not always. That is why the doctor reads the test together with an ultrasound or CT.
