$34 bucks and just 15 minutes is all someone could need to know if they have HIV or syphilis.

Researches from the University of Columbia put the mechanics from a lab test into a small device that can be attached to your smartphone, and test you for diseases. All the user does is attach the device to his or her phone, then all it needs is to prick your finger for a small sample of blood. Once that is done, place the collector’s chip onto the device and wait 15 minutes for it to receive the results. Here is a video to see how it works.

While this might be a little strange to some, devices like this are leading the way for healthier, safer sex.
