Students can get results confidentially, while the apparatus costs just 30 yuan

Students at Southwest Petroleum University are able to purchase cheap HIV test kits from vending machines on campus, which also sell edible goods such as instant noodles.

The kit, which costs 30 yuan ($4.40), consists of a plastic cup and a plastic tube. The user urinates into the cup and then draws the urine up into the tube, which has a serial number.
