allafrica.com - Researchers had developed the first non-invasive method of detecting malaria infection using a laser beam scanner. The painless test appears to be 100 percent accurate and does not require using any blood. Currently, the gold standard of malaria testing is examining a blood smear under the microscope for evidence of the deadly parasite. A diagnosis requires trained technicians, expensive equipment and time, things that are not always available in poorer and more remote parts of the world.
