We are starting to do drug testing in our office and I am not lab savvy. We will be using a dipstick method that will test for 12 different Class A drugs. This is what I think I should use: 80300, drug screen, any number of drug classes from Class A capable of being read by direct optical observation per date of service. Since we are testing for 12 different drugs, should it be 80300 x12. Any input would be greatly appreciated. Thanks!
