Background / Pre employment drug screen testing

Hi GuysThanks for this group.Anyone gone through this? really urgent!!!Guys, I just got the offer letter from XXX company but I am in India right now for vacation.I’ve been trying to reach eScreen (who is doing the drug screen for my new employer) but no luck. An email from XXX says that the Drug screen should be done within 48 hours of receiving the offer letter. It’s been 10 hours already, Do we have any other option to do it here in India through eScreen certified clinic, is there any eScreen certified clinic in India?. I’m sure that there should be a way, there are so many recognized drug screen clinics here in India (including Quest Diagnostics). I don’t know if eScreen will accept that or not. Do you have any idea about this? or Do you know anyone who can help us at this time?
