title: [Impact of a new parasitologic laboratory for malaria diagnosis on diagnosis and cost of malaria in a company setting: experience from Angola].
abstract: In malaria endemic areas treating every fever episode as a malaria onset would result in overdiagnosis with a margin of the error varying in function of epidemiological factors. When further compounded by overestimation related to errors in parasitologic diagnosis, clinical misdiagnosis leads to unwarranted hospitalization and inappropriate treatment. In a company setting this would mean unnecessary loss of employee work time. False positive diagnosis causes overestimation of chemoresistance, overconsumption of antimalarial drugs and underestimation of other infectious diseases. Judging from these high costs, it can be assumed that improving the reliability of parasitologic diagnosis would have a positive impact on the quality of clinical management, efficiency of antimalarial use and accuracy of epidemiological surveys. This assumption was confirmed by analysis of data following start-up of a parasitologic laboratory for malaria diagnosis in the health care clinic at Sonamet's fabrication yard in Lobito, Angola. Laboratory personnel receives expert training and audit findings demonstrate consistently reliable diagnosis. This experience underscores the need for reliable parasitologic diagnosis as a prerequisite for any large-scale malaria control program.
