Relative uncertainty of fluorescent measurements of PG-DNA adducts in low parasitaemia samples. Plot of the relative uncertainty calculated form the fluorescence readings at different parasitaemias shown in the Table 1. Results are displayed for infected red-cell cultures (IRBC, black square, dashed line), infected red-cell cultures diluted with peripheral blood (IRBC+WBC, white circle, solid line), and infected red-cell cultures diluted with peripheral blood and depleted of white-cells (IRBC+WBC/W, white square, dotted line). All samples were processed for removal of haemoglobin and detergents. Curves fitted using inverse first order polynomial equation, r2> 0.97.
