This parasitic infection, transmitted by triatomine bugs, is a concern in certain regions. Some blood banks screen for Chagas disease to prevent transmission.

Testing for Chagas disease typically involves a blood test to detect antibodies to the parasite Trypanosoma cruzi, which causes the disease. The most common method for diagnosing Chagas disease is through serological tests. These tests look for antibodies in the blood that the immune system produces in response to the presence of the Trypanosoma cruzi parasite.

It’s important to note that Chagas disease has acute and chronic phases, and the tests may be more accurate during specific phases of the infection. Additionally, the availability of specific tests and testing methods may vary by location and healthcare facility.
