Table 2 Application of dRT-PCR and cRT-PCR assays on field serum samples

From: A direct real-time polymerase chain reaction assay for rapid high-throughput detection of highly pathogenic North American porcine reproductive and respiratory syndrome virus in China without RNA purification

Method No. of specismen HP-PRRSV positive HP-PRRSV negative Positive rate, % Correlation, %
dRT-PCR 144 94 50 65.3 100
cRT-PCRa 144b 94 50 65.3 100
  1. aThe cRT-PCR data were provided by Yang [15].
  2. bThese samples had also been detected using immunochromatochemistry by Yang [15].
