if my home drug test kit gives me a negative result (clean) and later that day i test again and the place sends it to a lab, will they be able to determine if i have used recently? i plan on doing a home urine test kit today and maybe having to do another urine test again later for a program. please help
Lab urine test vs. home urine test?

Larry, that is kinda going to depend on how sensitive the test at the program is. The home tests are pretty good, but when they mail the UA to a lab, they screen for much smaller amounts. Not sure what you are taking right now, but if it is benzo, or pot, it can test positive for a about 6 weeks after last use. Methadone and suboxone test positive for a couple of weeks after last use. Most other things do clear the system enough for a quickie test in 3 to 8 days time, but a mail off test is usually really sensitive and checks for even minute amounts.

thank you pattishan61.
it will be over 6 and a half days clean at the time of the test on friday 2/25. i very rarely use cocaine and would not have if i knew about the test. i am planning on doing a home test on friday and later that evening taking the required scheduled test. it is an outpatient clinic. my concern is that if i get a negative at home and go forward with the lab clinic test, is there a chance that the lab test will return positive?

I guess there is always a slim chance but cocaine will speed metabolism up, not down like opiates, muscle relaxers, and benzos and it doesn't stick around in the fat layers. If I were you, I would still try to get in some light exercise, drink water and take hot baths in order to sweat out any residue. Good luck, hope you come out fine.
