0:00.0 | You're listening to live courtroom coverage of the trial of Karen Reed from the Hidden |
0:05.1 | Killers podcast and True Crime Today. Now, back to the courtroom. |
0:29.1 | Doctor, are you aware, I know your lab at Good Samadran did not do this process, but are you aware through your training experience of any sort of mathematical conversion that can be done from |
0:34.3 | a serum reading in milligram per deciliter to a blood alcohol concentration, a whole blood? |
0:39.3 | Objection. |
0:40.3 | I'm going to allow it. The door was open. |
0:43.3 | Go ahead, sir. |

1:16.6 | And when we test, we test the plasma, which is specifically testing the watery component. Now people have done studies like how much percentage |
1:32.0 | of you know of water is a serum versus whole blood. Basically to put it simple, there's more, |
1:40.1 | there's a higher percentage of water in the serum versus whole blood. |
1:45.0 | So a hospital result will always be a little bit higher than a test on whole blood. |
1:53.0 | It can be, I think the ratio, the conversion factor is anywhere from 1.1 to 1.18. |
2:03.8 | It's always, could be 18% or 11% higher in serum versus whole blood. |
2:09.9 | But we don't do it. |

2:11.9 | I will defer that to the experts. |
