There comes a time when you shop for drug tests that you may realize that people that are being sampled will try to tamper with the urine. While you don’t want to think that this will happen, you should never the less be proactive and prepared to ensure that each sample you take gets the accurate outcome that it deserves. We provide supplies that help prevent tampering and one of those is the integrity seal acetate film that will alert you when it is broken that the sample has been compromised. A drug test is going to be completely accurate when it is given and read correctly, as well as when the sample is true and has nothing added to it.
