it is a novel idea but many people will not use it.  if low cost labs like teranos are allowed to do testing, the question of accuracy and reliable come into question.  blood tests results must be accurate otherwise the diagnosis by the doctor might be wrong and possibly leading to more problems.  in medicine, cheap is not always better, you get what you pay for.  why gamble where you health is concerned, you have only one life and you want the best medical care that you can afford, saving $20 but having more health complications is not worth it.  Are you willing to gamble with your patients health?  In any profession there are good and bad people.  yes, some doctors over prescribe tests, etc. and some take advantage of the system by over billing.  as patients, we can only hope and pray that our physicians are sincere and honest and their primary concern is the health of the patient - believe majority of the doctors fall into this category.
