By now you may have already looked into other drug test kits and are ready to look at the 12-screen drug test. You may not need a 12-panel drug test if you just want to screen for the most common drugs like marijuana, cocaine, opiates, and methamphetamines. In that case, you may just want to go with drug testing supplies that have fewer panels on them, such as our 5-panel drug tests. However, if you are working in an environment where you need to monitor your employees more vigorously, then the 12-panel urine test may be just want you need to conduct your drug test. Drug testing panels like these can be shipped and sold from a drug testing supplies company like ourselves, and we even sell this particular drug test in bulk.
