An RFLE is not required for implied consent or search warrant DUI/D cases where the blood samples were collected using the DFS kit and the kit is mailed to DFS. If the kit is delivered via a hand to hand transfer to a DFS Laboratory (i.e., in person), an RFLE is required to document the chain of custody.
There is a DUI/D Submission Information sheet provided in newer kits that should be filled out and included with the submitted kit. If you have an older kit that does not contain the DUI/D Submission Information Sheet, you may access it here.
