Table 2 Consistency of outcomes in different PCR assays in relation to the amount of filter paper material used for extraction

From: Combined DNA extraction and antibody elution from filter papers for the assessment of malaria transmission intensity in epidemiological studies

Filter paper number Never positive (%) Positive in 1/3 PCR assays (%) Positive in 2/3 PCR assays (%) Positive in 3/3 PCR assays (%)
Single 80.8 (194/240) 2.9 (7/240) 5.4 (13/240) 10.8 (26/240)
Double 79.6 (191/240) 1.3 (3/240) 4.6 (11/240) 14.6 (35/240)
  1. The proportion (n/N) of positive PCR assays when aliquots of the same extracted material was used in three different PCR assays.
