So this is basically a post-mortem concentrations or samples that were hospital blood samples that were submitted for Mr. Floyd and we found fentanyl at 11 nanograms per milliliter and norefentanyl at 5.6 nanograms per milliliter. So this slide shows what the ratio of the parent drug to the metabolite is.

So this slide shows what the ratio of the parent drug to the metabolite is.

So 11 nanograms per ml divided by 5.6 to norfentanyl gave Mr. Floyd a ratio of norfentanyl of 1.96.

So 11 nanograms per ml divided by 5.6 to norfentanyl gave Mr. Floyd a ratio of norfentanyl of 1.96.

So Mr. Floyd's ratio is roughly just a little bit below the median ratio in DUI.

So Mr. Floyd's ratio is roughly just a little bit below the median ratio in DUI.
