Trypanosoma cruzi polymerase chain reaction (PCR) is widely used, but sensitivity varies widely. We compared PCR using 121/122 primers targeting kinetoplast minicircle DNA in whole blood, buffy coat, and clot from Bolivian women. Sensitivity was significantly higher in clot (60.1%) than buffy coat (46.5%) or whole blood (40%). The use of clot could simplify specimen collection while improving sensitivity.
