he impact of luminol on DNA profiling was not wholly
conclusive based on these results. At stronger concentrations of blood, neither of the formulation tested showed a
significantly negative effect on DNA, but did show an
increase in peak area compared to the control which was
statistically significant. At a weaker dilution of blood (1/
1,000), the effect of luminol seemed to become detrimental
to the DNA profiling process. In order to prevent biasing,
any samples showing poor morphology were not repeated;
therefore, an improvement in the profiles could be obtained
if optimisation was carried out.
