New portable HIV detector returning results in 10 minutes
|
A new portable device, invented by researchers at California's Palo Alto Research Center (PARC), is capable of performing an HIV test in less than 10 minutes.
The detector, as small as an iPod, could help monitor HIV/AIDS epidemics in rural African regions where currently access to testing is not available.
The prototype cost about $250 to build.
The pocket-sized device works with battery. It provides a full immune system check-up in less than 10 minutes.
"The quality of their test is great," said researcher Bernhard Weigl of PATH, an independent reviewer. "If you look at their graph, it pretty much looked like the graph you would get from a big instrument."
Mother Nature Network describes its method of operation as follows:
"The device works by analyzing a sample of blood small enough to be supplied by a pinprick to the finger. Laser technology scans the blood cells as they enter a tiny channel, and can identify the cells based on the light patterns that bounce off them. The idea is basically to count CD4+ T cells, which are the immune cells targeted by the HIV virus."
