home drug tests are not a reliable source
so you wasted your money try doing it
and sending it to a lab where they test
it better yet get every pot smoker you
know and can get a hold of to do it and
send it to a lab get a good exact ratio
Just goes to show that you need considerable education on how drug testing works. Because if you really knew what you were talking about, youd understand that:

1)To keep costs down, labs will perform an initial Immunoassay screen on the urine sample first. Only when the sample fails the initial I/A, that the sample undergoes a confirmation GC/MS and an exact quantitative value provided. The IA is a "pass/fail" deal and has no ability to provide a quantitative analysis.

2) The home THC test kits, being assays themselves, are just as reliable as the I/A's used at the labs for the initial screen. So if youre routinely passing home tests (with the first void of the day), you'll pass the initial I/A screen at any time. And when a urine sample tests negative on the initial I/A, the testing process is finished and no confirmation test will be performed.

As I stated previously, the Drug Testing forum is not a playground. Theres careers, families, and freedoms at stake and factual info is vital here. If this idea doesnt suit you, then perhaps the Drug Testing forum is not for you.
