What would cause a drug test to be positive for t h c if I don't do drugs?

Hello c:

I don't know.. Ask for another test, or take the sample to your OWN lab.

What type of test was it?

It was a standard UA dip test. We requested a lab test be done gc/ms however they are claiming that they did one only after we protested the results. I don't think they actually did one because we paid for one the very next day after the first test was done and it was negative. The lab we used is a very reputable one all the hospitals in our area use the same lab company. They claim the first urine same came back from the lab with a 34 screen with a 15 screen cut off, but I don't know what that means English! Do you have any Idea what the numbers mean? I'm sure it's a low number but since my son doesn't do drugs I think the number is false.
