Federal researchers say they've developed a human identification test that's faster and possibly cheaper than DNA testing. It would be a handy new weapon in the arsenal for detectives, forensic experts and the military, though no one expects it to replace DNA analysis -- and its promoters say it is not intended to. The new method analyzes antibodies. Each person has a unique antibody bar code that can be gleaned from blood, saliva or other bodily fluids. Antibodies are proteins used by the body to fend off viruses or perform routine physiological housekeeping.
