What if I do not want to take any tests? Do I have any legal grounds to stand on? Do I lose relinquish all my rights when driving?
They will have a judge issue a warrant for your blood if you refuse, so yes, that will happen. However, if you take a field sobriety test and fail, then subsequently take a blood test and pass, the officer will testify you must have been under some sort of drug the test didn’t pick up on, and, in his opinion, you were under some mind altering influence and you could and probably will be convicted.
IANAL, but if you refuse a blood or breathalyzer, you will automatically receive a license suspension in many states. This will occur even if a warrant is obtained, you are blood or breathalyzer tested and found to be under the legal limit. This is the doctrine of implied consent. By obtaining a license in a state with implied consent, you are implicitly giving your consent to be tested for alcohol. If you subsequently refuse, your license is suspended, even absent any criminal conviction. I know this is the law in Pennsylvania where I live; obviously laws vary in other states.
