Malaria Diagnosis and Prognosis: To diagnose malaria only on the basis of symptoms is difficult. Diagnosis of malaria is generally made by examining a sample of blood to be smeared on glass slides. These blood smears will be stained with special chemicals and examined for Plasmodium parasites. Blood tests will be done to find out whether malaria has affected levels of red blood cells and platelets.
