Description
Why It’s Done
The test is typically done to:
• Diagnose echinococcosis, particularly in individuals with symptoms such as:
o Abdominal pain or discomfort (if the liver is affected)
o Chest pain or cough (if the lungs are affected)
o Fever, nausea, or weight loss.
• Confirm infection when imaging studies (e.g., ultrasound or CT scans) show signs of cysts in organs like the liver or lungs, but further confirmation is needed.
• Identify Echinococcus infection in people who have been exposed to contaminated food, water, or animals, particularly in endemic regions.
• Monitor treatment progress for individuals undergoing therapy for hydatid disease, ensuring the cysts shrink or resolve.
Preparation
• No special preparation is typically needed before the test, unless the sample needs to be collected during a specific procedure.
• The tissue or fluid sample may be collected through a needle aspiration from a suspected cyst site or obtained from surgical biopsy.
• If a serum sample is used for indirect diagnostic tests, a standard blood draw will be required.
• In cases of imaging studies or when cysts are suspected, a CT scan or ultrasound may be performed to guide sample collection.
• Ensure the doctor is aware of any recent travel to endemic regions or exposure to livestock, as this is important for interpreting the results.
