Do they sell home tests that deterimne the ng in your urine?

If anyone can point me int he direction of something liek that I'd be appreciative.

Because they are assays, all home test kits are a pass/fail endeavor and lack the ability to give a quantitative value. In order to obtain quantitative values, the urine sample must undergo the GC/MS at the lab.

Yes. Get it from your local drug store for about $20. It's called - First Check Marijuana Drug Test Kit. You can mail off your specimen if it shows a failing line. Very useful.

To clarify what DDM had pointed out above, if you test positive on the First Check kit, you can mail your urine sample off for the confirmation test with a quantitative value provided.

DDM: When you sent your specimen off, where there any shipping charges involved?

[deandavidmartin]

Yes, it was about $4 standard shipping, I always took it to the post office in person to make sure the right postage was applied. When they asked me if there were any liquids in the box, I always said "No". I'm not sure what would happen if I said "Yes", probably nothing or maybe they would mark it different and charge more, I don't know. Sometimes they didn't ask. On the instructions, it says once the lab receives the specimen, allow 5-7 days for results. However, in my experience it was less that 2 days and the results were available. The cut off is 15ng. My failure was 21ng (at 19 days sober) and 2 days later my levels were below 15ng. Yes, I took the 2nd test 2 days later, as the first test appeared to show a "ghost" line. I've got a post some where around here documenting the whole thing..
