Table 4 Metrics of qPCR efficacy compared to the positive or negative babesiosis disease state as determined by IFA and microscopy

From: A novel quantitative PCR detects Babesia infection in patients not identified by currently available non-nucleic acid amplification tests

qPCR Metrics Point Estimate 95% Confidence Interval (Lower Bound, Upper Bound)* Standard Error
Sensitivity 96.2% (91.1%, 100.0%) 2.6%
Specificity 70.5% (62.9%, 78.1%) 3.9%
Positive Predictive Value 55.4% (45.3%, 65.6%) 5.2%
Negative Predictive Value 98.0% (95.3%, 100.0%) 1.4%
  1. *Confidence intervals with upper bounds >100% are shown as 100%
