Thanks, but what do you make of two separate manufacturers strips with opposite results? One with two solid lines and the other with only one line. Both tests done at the same time using the same sample. And on one strip you almost need to use your imagination or hold it at certain angles to see it? Are the comments I've read that say " a very faint line demonstrates thc levels at or near the cutoff? Is this totally bogus?. If I was the lab I would question such a faint line and find it hard not to find it positive when it is so hard to see. I get the feeling that I have one set of strip tests that don't have sufficient color on the test line. Your thoughts?
drvrcrzy Reviewed by drvrcrzy on . Different test different results I have used several brands of THC strip tests. On one recent batch the second line is very faint even when testing a known negative and even tap water while another brand test used at the same time has a nice bold line. The test with the very faint line seems to be very sensitive to even the slightest amount of THC. After getting repeated negative results, then taking as little as one or tow puffs - the line becomes almost invisible. At the same time the other brand shows a clear second line. Rating: 5
