C.__For purposes of evidence in proceedings other than those arising under section 10701, subsection 1, it is presumed that a person was under the influence of intoxicating liquor when that person has:

(1) For a person 21 years of age or older, a blood- alcohol level of 0.08% or more by weight; and

(2) For a person less than 21 years of age, any amount of alcohol in the blood.

D.__Percent by weight of alcohol in the blood is based upon grams of alcohol per 100 milliliters of blood.

5.__Administration of tests.__Persons conducting analyses of blood, breath or urine for the purpose of determining the blood- alcohol level or drug concentration must be certified for each purpose by the Department of Human Services under certification standards set by that department.

A.__Only a duly licensed physician, registered physician's assistant, registered nurse or a person certified by the Department of Human Services under certification standards set by that department, acting at the request of a law enforcement officer, may draw a specimen of blood to determine the blood-alcohol level or drug concentration of a person who is complying with the duty to submit to a chemical test.__This limitation does not apply to the taking of breath or urine specimens.__When a person draws a specimen of blood at the request of a law enforcement officer, that person may issue a certificate that states that the person is in fact a duly licensed or certified person as required by this subsection and that the person followed the proper procedure for drawing a specimen of blood to determine the blood-alcohol level or drug concentration.__That certificate, when duly signed and sworn to by the person, is admissible as evidence in any court of the State.__It is prima facie evidence that the person was duly licensed or certified and that the person followed the proper procedure for drawing a specimen of blood for chemical testing, unless, with 10 days' written notice to the prosecution, the defendant requests that the person testify as to licensure or certification, or the procedure for drawing the specimen of blood.
