Summary: The authors of this study evaluated the effect of changing the algorithm for serological diagnosis of T. cruzi infection in departmental-level public health laboratories and the National Reference Laboratory of Colombia using a descriptive, cross-sectional study based on secondary sources from 2015 to 2021. Using information from 33 public health laboratories, they found that the 2017 change in the algorithm had positive effects on access to diagnosis since it facilitated the use of a second test and resulted in increased diagnostic coverage. Colombia's laboratories now have access to a simple, timely, quality algorithm that could be implemented in almost any clinical laboratory in the country.
