In an initial field trial in Rwanda, the "mChip" rapid field test detected HIV and syphilis with reliable accuracy, according to a study published in Nature and reported by The Washington Post. The credit card-sized mChip analyzes a blood sample within 20 minutes. Current testing techniques in Rwanda require blood to be sent to a central laboratory with a turnaround time of days or even weeks. Researchers expect that the device will cost less than traditional testing and that it will eventually be usable to detect hepatitis B and C, herpes, gonorrhea and chlamydia.
