It is possible that the police either obtained a subpoena for a blood draw at the hospital, or that they will subpoena test results from the hospital to try to determine if there is a basis for a DUI charge. The driver can try to find out from the hospital if the treatment records show a court-ordered blood draw or if the police have requested any test results; or the driver can wait and see what happens, contacting a criminal defense lawyer if notified of a DUI charge.
