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.

ELISA is an antibody test.

The 100% detection refers to the detection of the antibodies, not the general detection of HIV infection.
