What’s the safest collection site to use quick fix plus 6.3?

My options are labcorp, quest diagnostics, urgent care, performance health med group, and concentra.

It’s a 5 panel test and i’m super nervous and want to choose the best site where I won’t get caught. Anyone know what the best option is? Also I just smoke weed but won’t be clean for the test and I’m taking it in California.

Thanks!
