The sample or samples must be taken by a physician, board certified pathologist, the county coroner or a designated representative of the county coroner.
(2) Whenever a postmortem blood sample is collected, all practical precautions to ensure a representative, uncontaminated sample must be employed. Care must be taken to avoid contamination of the sample by gastrointestinal contents if it is necessary to sample heart blood. There must be adequate mixing of the blood sample before withdrawal. If a heart blood sample is taken without autopsy, precautions against dilution of the blood with pleural or pericardial fluids must be employed.

If a heart blood sample is unattainable, the sample of choice will be urine. Any sample to be drawn will be an uncontaminated sample.
