A $34 Smartphone Gadget That Can Detect HIV in 15 Minutes

> They found that the test rivaled gold standard lab tests and was able to correctly detect infections 92 to 100% of the time. Although it missed one case of syphilis and falsely diagnosed syphilis infections 14% of the time, the device is still extremely useful because false positives would be picked up later on after the patient is sent for further tests and treatment.

If you use it in a normal party (were I assume that less than the 1% have syphilis) then more than the 90% of the detections will be false positive. Good for amusement of everyone but the subject case :(.

It is only useful as a first screening test, take it only as a suggestion to take a serious test.
