Trials of an affordable, credit-card-sized blood test kit that can detect infections within minutes could radically improve health care worldwide.
The device, developed in the US and called mChip, consists of ten individual zones on which only one drop of blood needs to be placed for analysis.
Prototypes of the device, tested on hundreds of patients in Rwanda to test for HIV or syphilis, were accurate 100 percent of the time.
The device's developers claim that the ability to quickly obtain blood test results, unlike conventional tests that often require days or even weeks to wait, can improve the prevention of the spread of HIV and STIs.
