DNA (Deoxyribonucleic Acid) Diagnosis

If you are sick, the doctor takes a culture. Perhaps five days later he finds out what is infecting you. He cannot treat you until then. If, however, he could do DNA analysis of the infecting agent right in his office, he might know within hours. In principle, such machines should already exist. It is probably just a matter of mass production bringing costs down.
