I am an expert in medicine, double board certified, US doctor.
I will be glad to answer this for you.
Chances, given studies, are better than 50/50 that you will pass.
Most studies show an actual detection time up to 50 hours, not the 70 or 80 as advertised by the lab company.
So, you will be beyond this threashold.
Not that you can't fail, but that the statistical odds are on your side.
You can't speed up the elimination of the markers, but, you are still in pretty good shape for the test.
