I know of at least one person who got hit by the test strips. He used transmission fluid to fill his filters when he changed them. The little bit that gets returned to the tank was enough to snag him. Granted, he was driving a 1 ton dually pickup and not a MB. Chances of us getting out tanks tested are pretty slim. Hopefully the MMO uses a different dye.
