...1/2 of new HIV infections are from people who would test negative in this test... I'm curious what the article means when it says "Researchers at Columbia University claim the mChip has a 100 percent detection rate." Are you sure the test is working the way you think it works? Could it be DNA-based rather than antibody-based?

Yup, I'm sure. The Nature article says it's an ELISA test. http://www.nature.com/nm/journal/vaop/ncurrent/full/nm.2408.html http://www.nature.com/nm/journal/vaop/ncurrent/full/nm.2408.... ELISA is an antibody test. http://en.wikipedia.org/wiki/ELISA http://en.wikipedia.org/wiki/ELISA The 100% detection refers to the detection of the antibodies, not the general detection of HIV infection.
