Boston scientists have developed a cheap, highly accurate test that can be used to diagnose conditions by detecting protein biomarkers in subjects' DNA. The test could be as simple to use as a home pregnancy testing kit, according to the researchers from the Wyss Institute at Harvard University and US's Children's Hospital. In experiments, the method was used to detect prostate-specific antigen and to screen between different strains of the Dengue virus in less than an hour. It reduced false positives to nearly zero and achieved lab-quality sensitivity.
