A test for the presence of Echinococcus IgG and IgM antibodies is done to see if the body has produced any in response to the presence of these tapeworms. The disease is brought on by unintentional consumption of Echinococcus eggs, which results in the development of cysts in the liver or lungs. The test, along with additional imaging studies, will offer unmistakable evidence of the cysts presence. The presence of antibodies is checked in the bloods serum or plasma. "An electrocardiogram (ECG) is a medical test that detects heart problems by measuring the electrical activity generated by the heart as it contracts. A doctor may recommend an ECG for people who may be at risk of heart disease because there is a family history of heart disease, or because they smoke, are overweight, have diabetes, high cholesterol or high blood pressure. A doctor may also recommend an ECG for people who are displaying symptoms such as chest pain, breathlessness, dizziness, fainting or fast or irregular heartbeats.The ECG is a safe and non invasive procedure with no known risks."
