Question - I sent UA after I saw a very faint line to be confirmed on the First Check. I called for test results and they said it was negative. How are these tests confirmed in the laboratory? Does anyone know? Thanks
hemi40 Reviewed by hemi40 on . Upcoming coming UA for employment...... I have a question....... I smoked for about 9 nine days while away on vacation in February. I took a First Check home test on April 29, 2008 that showed a questionable line. I sent off for confirmative testing. Today, I tested again with First Check and it showed very strong pink / purple line for THC. I have a uring drug screen on May 21, 2008. Do I have anything to worry about? What are the cutoffs for most UA pre-employments? Thanks Rating: 5
