Rates of Pfs 25-mRNA retrieved from DBS filter paper samples subjected to different storage conditions. Analysis was performed from extracted DBS filter papers and standardised against fresh whole blood at the time of sample preparation (100%). QT-NASBA-1/TTP was used as a surrogate parameter for the amount of mRNA. Depicted retrieval rates for each time point are averaged over all gametocyte densities (10-1 to 103 per μl) and plotted in a single column. Statistical significance and storage conditions are labelled above the individual charts.
