Requesting to Have Your Blood Retested
When blood is drawn in a DUI case, you can request to have the blood retested

the defense’s forensic expert, or to the expert’s representative
or lawyer for retesting. However, just because the defense requests a
portion of the blood, it doesn’t guarantee that it will be lowered.
It could come back lower, the same, or even higher.
