Interpretation

Negative:

No antibodies to Trypanosoma cruzi (Chagas disease) detected. Antibodies to T cruzi may be absent during acute infection, therefore a negative result cannot be used to rule out recent infection. Repeat testing in 3 to 4 weeks is recommended if clinically indicated.

Indeterminate:

Repeat testing in 2 to 3 weeks if clinically indicated.

Reactive:

Antibodies to T cruzi detected. Result is not diagnostic. Supplemental testing by a second, different T cruzi serologic assay is recommended.
