If the patient meets the clinical inclusion criteria, s/he will be examined for blood inclusion criteria (P. Falciparum mono-infection, parasite density and haemoglobin levels). Thick and thin malaria smears will be taken on the same slide in duplicate and one smear will be stained. At the same time, a capillary blood sample will be taken on Fast Technology for Analysis (of nucleic acids) or FTA Cards for PCR analysis. The patient will wait for the thick smear result.
