Table 1 Sensitivity and specificity of the real time qPCR in blood and serum samples

From: Usefulness of real time PCR to quantify parasite load in serum samples from chronic Chagas disease patients

  Blood samples Serum samples
ELISA + ELISA - ELISA + ELISA -
qPCR + 39 (97.5%) 0 (0%) 38 (95%) 0 (0%)
qPCR - 1 (2.5%) 20 (100%) 2 (5%) 20 (100%)
Total 40 20 40 20
  1. To calculate Sensitivity and Specificity values, serology was considered as gold standard.
