Will I p my hair follice test??

I took a hair follicle test on 5/21/2010. I took a presription at the beginning of mar 2010 of lortab,soma and klonopin. I had a hair cut to 1 1/4 inches before the test. They didnt ask about prescriptions nor did they have a place to write them. What are the chances of ping? If a positive result comes back will i have the chance to explain about the scripts that i had over 2 months ago?
