The U.S. Food and Drug Administration has approved the Binax NOW Malaria Test, the first rapid test authorized for laboratory use in the United States.
Standard laboratory tests for malaria require identifying parasites in a blood sample under a microscope -- a difficult task requiring training and experience.
The FDA said the new test is significantly faster and easier to use, producing results in 15 minutes after a few drops of whole blood are placed on a dipstick.
The test can also differentiate the most dangerous malaria parasite, Plasmodium falciparum, from less virulent malaria parasites. Results, however, still need to be confirmed using standard microscopic evaluation, the FDA noted.
Malaria was eliminated in the United States during the 1950s but citizens can become infected while traveling in other countries. There were 1,528 new U.S. cases of malaria reported during 2005, including seven deaths. The FDA said nearly all deaths can be prevented if the infection is diagnosed and treated early.
FDA scientists found the Binax NOW test was 95 percent accurate compared with standard microscopic diagnosis in a multi-center study.
The test is manufactured by Binax Inc., a subsidiary of Inverness Medical Innovations Inc.

Malaria researchers identify new mosquito virus
Researchers at the Johns Hopkins Bloomberg School of Public Health's Malaria Research Institute have identified a previously unknown virus that is infectious to
Anopheles gambiae—the mosquito primarily responsible for transmitting malaria. According to the researchers, the discovered virus could one day be used to pass on new genetic information to An. gambiae mosquitoes as part of a strategy to control malaria, which kills over one million people worldwide each year. The study was published August 22 online in the peer-reviewed open access journal
PLoS Pathogens.
Experiments could lead to new treatments for neuroblastoma
Neuroblastoma is one of the most devastating diagnoses a child can receive. The cancer's victims average 2 years old when the disease is detected, most often by a parent feeling a lump in a child's abdomen. By then, the disease has often reached an advanced stage, and advanced neuroblastoma kills more than 50 percent of the children in whom it develops, despite aggressive treatment with surgery, chemotherapy and radiation.
