There are tests that are done lab on chip but not everything can be done this way. Even a basic chem panel for your blood is 20 analytes. The mechanism for these tests are all different. Also the pre-testing prep for the blood is different. Some tests need whole blood with anti coagulant, some need serum spun down from whole blood, some need other treatments. This is a 50 billion dollar industry. If it was easy to prick someone's finger and run an entire comprehensive panel you better bet it is not going to be found by some teenager dropping out from college. Sure software has been done like this before, but this is hard science and engineering. If someone would have posted on HN that a college dropout without a computer engineering degree is making servers that run on 1/10th the power, people would laugh them off unless they really made one. As mentioned too cost is a big factor. It is at the point now where a basic blood panel is reimbursed at the same cost as a meal at a fast food restaurant. Even if this technology was not vaporware, it would have to be around the same price.
