So,I have a question regarding pre-employment URINE nicotene test/cotinine test. I have been free and clear of cigarettes for 3 days and have to test in 5 days. I have been drinking approx a gallon of water daily and totally stayed free and clear of any type of second hand smoke. I bought an online urine cotinine test where I tested negative. However, the level I test could only tell me that my urine concentration was below 200 ng/ml. After doing some research online, I feel like the standard for a negative test result is less than that off 200 ng/ml. Does anyone know the standard they test in urine. Also, do you think if my levels are already below 200, that I'd be able to pass the test in 5 days? Please no cruel posts or judgements...I just want facts!
