When a person submits to a blood test at the request of a police officer under section 4511.191 [4511.19.1] of the Revised Code, only a physician, a registered nurse, or a qualified technician or chemist shall withdraw blood for the purpose of determining its alcohol, drug, or alcohol and drug content. This limitation does not apply to the taking of breath or urine specimens. A physician, a registered nurse, or a qualified technician or chemist may refuse to withdraw blood for the purpose of determining the alcohol, drug, or alcohol and drug content of the blood, if in the opinion of the physician, nurse, technician, or chemist the physical welfare of the person would be endangered by the withdrawing of blood.

Such bodily substance shall be analyzed in accordance with methods approved by the director of health by an individual possessing a valid permit issued by the director of health pursuant to section 3701.143 [3701.14.3] of the Revised Code.

This division does not limit or affect a criminal prosecution or juvenile court proceeding for a violation of division (B) of this section or of a municipal ordinance substantially equivalent to division (B) of this section relating to operating a vehicle with a prohibited concentration of alcohol in the blood, breath, or urine.

(3) Upon the request of the person who was tested, the results of the chemical test shall be made available to the person or the person's attorney or agent immediately upon the completion of the chemical test analysis.

The person tested may have a physician, a registered nurse, or a qualified technician or chemist of the person's own choosing administer a chemical test or tests in addition to any administered at the request of a police officer, and shall be so advised. The failure or inability to obtain an additional chemical test by a person shall not preclude the admission of evidence relating to the chemical test or tests taken at the request of a police officer.

(ii) The prosecution may introduce the results of the field sobriety test so administered as evidence in any proceedings in the criminal prosecution or juvenile court proceeding.

(iii) If testimony is presented or evidence is introduced under division (D)(4)(b)(i) or (ii) of this section and if the testimony or evidence is admissible under the Rules of Evidence, the court shall admit the testimony or evidence and the trier of fact shall give it whatever weight the trier of fact considers to be appropriate.

(c) Division (D)(4)(b) of this section does not limit or preclude a court, in its determination of whether the arrest of a person was supported by probable cause or its determination of any other matter in a criminal prosecution or juvenile court proceeding of a type described in that division, from considering evidence or testimony that is not otherwise disallowed by division (D)(4)(b) of this section.

(5) Any physician, registered nurse, or qualified technician or chemist who withdraws blood from a person pursuant to this section, and any hospital, first-aid station, or clinic at which blood is withdrawn from a person pursuant to this section, is immune from criminal liability, and from civil liability that is based upon a claim of assault and battery or based upon any other claim that is not in the nature of a claim of malpractice, for any act performed in withdrawing blood from the person.
