Parasitological diagnosis of malaria has for a long time been based on microscopic detection of asexual malaria parasites on a blood smear from a person suspected to have malaria. But many areas lack laboratory support to provide malaria microscopy. Even where it is available, many factors affect the quality of microscopic diagnosis: the experience and training of the microscopist; the quality of the slide preparation, staining, and reading; the quality of the equipment; and the availability of electricity and reagents...
