(i) When so directed by a law enforcement officer through a written statement, the medical professional shall withdraw the sample of blood as soon as practical and shall deliver the sample to the law enforcement officer or another law enforcement officer as directed by the requesting law enforcement officer as soon as practical, provided the collection of the sample does not jeopardize the person's life, cause serious injury to the person or seriously impede the person's medical assessment, care or treatment. The medical professional authorized herein to withdraw the blood and the medical care facility where the blood is drawn may act on good faith that the requirements have been met for directing the withdrawing of blood once presented with the written statement provided for under this subsection. The medical professional shall not require the person that is the subject of the test or tests to provide any additional consent or sign any waiver form. In such a case, the person authorized to withdraw blood and the medical care facility shall not be liable in any action alleging lack of consent or lack of informed consent.
Such sample or samples shall be an independent sample and not be a portion of a sample collected for medical purposes. The person collecting the blood sample shall complete the collection portion of a document, if provided by law enforcement.
