New HIV test takes minutes, costs $1.
The mChip was created at Colombia University, and is so simple it can be used by almost anyone. A small sample of blood is dropped onto the microfluidics based chip, and a result is displayed in around 15 minutes.
The chip can test for syphillis and HIV and has a 100% detection rate, although up to 6% can be false positive results, requiring the need for a re-test. While that may sound like a lot of false positives, it is still around the same amount of error as traditional tests.
While the chips can’t yet be purchased through your local doctor, researchers hope they will find widespread use in Africa. A prostate detecting chip has already been approved for use in Europe.
