Being an extract kit...first of all it would have been difficult to take an OG anyway (thoroughly mixing is an issue), but it might be done at 1.020 (some just stop there). The easiest thing to do would be to let it sit for another week just to be safe, and let the yeast clean things up.
Bacteria are the only culture some people have.
