Overview of the Chagas Disease Serology (S.American Trypanosomiasis) T. Cruzi
The Chagas Disease Serology test detects antibodies produced against Trypanosoma cruzi, the parasite responsible for Chagas disease.
The test contains 1 biomarker: Chagas Disease Serology (S.American Trypanosomiasis) T. Cruzi.
Chagas disease is also known as American trypanosomiasis.
It is primarily associated with Latin America, where Trypanosoma cruzi is traditionally transmitted through infected triatomine insects, sometimes called kissing bugs.
Transmission can also occur from mother to baby during pregnancy, through infected blood products or organ transplantation and, less commonly, through contaminated food or drink.
Following infection, an acute phase occurs.
This may be mild or completely unnoticed.
The infection can then progress to a chronic phase lasting for many years or decades.
Many people remain asymptomatic throughout chronic infection.
Others can eventually develop significant complications affecting the heart or gastrointestinal system.
Cardiac Chagas disease can cause electrical conduction abnormalities, arrhythmias, cardiomyopathy and heart failure.
Digestive involvement can impair the nerve supply to the oesophagus or colon and lead to enlargement or motility problems.
Serological antibody testing is particularly important in chronic infection because circulating parasite levels can become very low.
A reactive antibody result provides evidence of previous or current Trypanosoma cruzi infection but should not automatically be treated as a final diagnosis based on one assay.
Confirmation using a second serological method based on different antigens or methodology is generally recommended when chronic Chagas disease is being diagnosed.
Results should therefore be interpreted alongside country of birth, residence history, travel, maternal history, transfusion history and relevant cardiac or gastrointestinal findings.
What Does the Chagas Disease Serology (S.American Trypanosomiasis) T. Cruzi Test Check?
This test measures 1 biomarker.
Chagas Disease Serology (S.American Trypanosomiasis) T. Cruzi
Detects antibodies produced against Trypanosoma cruzi, supporting investigation of previous or chronic Chagas infection where the epidemiological and clinical history is appropriate.
Who May Benefit From the Chagas Disease Serology (S.American Trypanosomiasis) T. Cruzi Test?
Testing is most appropriate where geographical, family or clinical history creates a meaningful possibility of Trypanosoma cruzi infection.
People born in a Chagas-endemic region - Infection may have occurred many years previously without producing obvious acute symptoms.
People who lived for prolonged periods in endemic areas of Latin America - Long-term residence can create meaningful exposure risk.
People who lived in rural housing where triatomine insects were present - Traditional housing can provide environments in which vector transmission occurs.
People whose mother has or may have Chagas disease - Congenital transmission can occur during pregnancy.
People with unexplained cardiomyopathy and relevant geographical history - Chronic Chagas disease is an important potential cause of cardiac muscle damage.
People with unexplained conduction abnormalities or arrhythmias after relevant exposure - Cardiac electrical abnormalities can develop years after infection.
People with unexplained oesophageal or colonic dysfunction and epidemiological risk - Chronic digestive Chagas disease can affect gastrointestinal motility.
People with previous blood transfusion or transplantation in an appropriate exposure setting - Transmission through infected blood or organs has occurred historically.
People with a previous reactive Trypanosoma cruzi test requiring further assessment - Specialist serology can contribute to confirmation.
People specifically advised to obtain Chagas serology - Testing can be arranged where an infectious-disease, tropical-medicine or cardiology clinician has requested it.
How to Prepare
Do not alter prescribed medication in preparation for serology.
A positive screening result may require confirmation using another serological method and further clinical assessment.
Symptoms and Reasons to Consider the Chagas Disease Serology (S.American Trypanosomiasis) T. Cruzi Test
Chronic Chagas disease can remain completely asymptomatic for many years, making exposure history particularly important.
No symptoms despite past residence in an endemic region - Chronic Trypanosoma cruzi infection can remain clinically silent for decades.
Unexplained palpitations with relevant geographical exposure - Cardiac Chagas disease can affect the heart's conduction system.
Unexplained fainting or near-fainting with previous endemic exposure - Significant arrhythmias can occasionally occur in chronic cardiac disease.
Cardiomyopathy without a clear cause - Trypanosoma cruzi infection may form part of the differential diagnosis when epidemiological risk exists.
Heart failure developing in someone with relevant exposure history - Chronic Chagas cardiomyopathy can impair cardiac function.
Progressive difficulty swallowing with appropriate epidemiological risk - Digestive Chagas disease can affect oesophageal motility.
Severe chronic constipation with relevant geographical exposure - Colonic nerve dysfunction and enlargement can occur in digestive Chagas disease.
A mother or close family member diagnosed with Chagas disease - Congenital and shared geographical exposure can justify individual assessment.
A previous uncertain Chagas antibody result - Further serological assessment may be needed.
These symptoms have many possible causes and should not be attributed to Chagas disease solely on the basis of exposure history.
Significant arrhythmias, fainting, chest pain, severe breathlessness or advanced gastrointestinal symptoms require appropriate medical assessment regardless of the serology result.
How to Book Your Chagas Disease Serology (S.American Trypanosomiasis) T. Cruzi Test
Booking your Chagas Disease Serology test with London Blood Tests is straightforward.

Select the specialist Trypanosoma cruzi antibody test.
Select your sample collection option
Choose an in-clinic blood draw or professional home or hotel phlebotomy depending on availability.

Receive your results securely
Your authorised result is delivered securely for interpretation with your exposure and clinical history.
When Will I Receive My Results?
The expected specialist turnaround for Chagas Disease Serology is approximately 11 days after your sample reaches the laboratory.
This is a specialist parasitology serology assay and requires longer laboratory processing than routine blood chemistry.
The turnaround begins once the sample has arrived and been accepted by the laboratory.
Analysis, internal quality control and laboratory authorisation must be completed before the report can be released.
If the initial result is reactive and confirmation using a second serological method is required, the complete diagnostic pathway may take longer than the standard 11-day reporting estimate.
Understanding Your Results
A negative result means antibodies to Trypanosoma cruzi were not detected by the assay used.
When testing is performed sufficiently long after potential exposure, this makes chronic Chagas infection less likely.
During very early acute infection, however, antibodies may not yet be fully developed and direct parasite detection can be more appropriate.
A reactive or positive result indicates antibodies consistent with Trypanosoma cruzi exposure.
Because no single serological assay is perfect, chronic Chagas diagnosis generally requires confirmation using another test based on different antigens or methodology.
A confirmed positive antibody result does not determine whether cardiac or gastrointestinal complications have developed.
People with confirmed infection may require additional evaluation including ECG, cardiac imaging and other investigations according to their individual circumstances.
Serology can remain positive following previous treatment, so antibody persistence does not necessarily mean that treatment has failed.
