Just got the lab results from my sample taken at 18 days clean (1st void) and it was 86 ng/ml. This is significantly lower (43 ng/ml less or 1/3 lower) than my first test 4 days earlier where the lab test results were 129 ng/ml (afternoon sample), so I am hoping that two weeks later (this week), my level will be below the cutoff. As with the first test, I also got a faint line on the at home test with the second test and still tested high for the lab test. I am curious to what this may mean and remain unconvinced of the validity of the at-home tests. I am still waiting on the results from the third sample I sent off to the lab (taken in the morning 25 days clean with a decently visible line on the at-home strip), but I am not sure if I will get the results back in time. I took a fourth at-home test yesterday in the morning (30 days clean), and again a decently visible line showed. Does it sound like I am good to go? Should I mess with trying to dilute before taking the test (if in fact I do have to take a UA test, I still have not been informed of the details of the medical examination, if it will include a drug screen, and if so what type)? I am thinking about just drinking 32 oz the morning of the test if I have to take one and popping a few vitamin pills. Does this sound reasonable for my situation?
