Blood Drug Testing

Home drug test accuracy?

How accurate is the First Check THC test? I passed two First Check home kits for THC and just want to be sure I'll be good for an actual lab test for a job. Smoked 8 days ago, passed one test yesterday and another two days prior. My lab test is tomorrow.

1. home test show false negatives all the time
2. Home tests arent reliable.. Lab tests on the other hand are. There are a range of tests that could be done to detect cannabis- Urine- Cannabis stays in the urine for 3 to 7 days, up to 30 days after heavy use and/or in users with high body fat Hair-up to 90 days Blood-2–3 days in blood, up to 2 weeks in blood of heavy users. Hope this helps xx
