Trypanosoma Cruzi IgG

What is the purpose of this test?

This test detects IgG antibodies against Trypanosoma cruzi, the parasite responsible for Chagas disease. It helps confirm chronic infection, particularly in asymptomatic individuals or those with cardiac or digestive manifestations.


When is it recommended?

The test is recommended for people with possible exposure in endemic areas of Latin America, blood donors, organ transplant candidates, or individuals with unexplained cardiac symptoms.


How is the test done?

A blood sample is analyzed using serological assays like ELISA to detect T. cruzi-specific IgG antibodies.


What do the results mean?

A positive result indicates past or chronic infection with T. cruzi. Negative results suggest no exposure, although early infections might not be detected.


What follows after a positive result?

Treatment with antiparasitic agents like benznidazole may be initiated. Further cardiac evaluations such as ECG and echocardiography are often performed.
