Now, gum swab to spot HIV

A simple gum swab in place of an invasive blood test can now tell whether you are HIV positive. What's even better, the test results will be out in just 10-20 minutes. In a breakthrough that could replace the present day HIV antibody test through blood taken from the finger or the arm, a team of Indo-Canadian scientists has successfully tested the world's first salivabased HIV test, with an accuracy rate of nearly 100%.
