### Human:\nwhy do some states require doctor's orders for a blood test while others do not? . i currently live in a state (in the u. s. ) where doctor's orders are required in order to get a blood test even if you're willing to cover the entire cost of the test yourself. in a couple of months i'll be moving to a different state where you can literally walk into a clinic and get a blood test without consultation of any kind. is there an ongoing debate about restricting blood tests and why might state governments want to restrict them?\n\n### Assistant: in america each state has the right and privilege of setting their own laws or regulations and this includes regulations related to the practice of medicine pharmacy dentistry or nursing.
