Every employer should make sure that the workplace is free from those who abuse or depend on substances such as alcohol or illegal drugs. In order to prevent drug abuse among employees they can introduce an effective drug testing program using multi-panel drug test kits. They can be used to detect two or more drugs as opposed to single-panel drug test kits, which detect only one drug. They can detect up to 12 drugs in one go including the most widely used ones. Therefore, there is no need of circular stapler. This ensures that the substance abusing employee cannot go undetected. They can detect commonly abused drugs such as marijuana, opiates, methamphetamine, amphetamines, oxycodone, phencyclidine, barbiturates, buprenorphine, MDMA (ecstasy), tricyclic antidepressants, benzodiazepines, methadone, propoxyphene (PPX), etc. Effective when used for random testing: Using these test kits, random testing could be made a more potent tool to deter substance abuse among employees. Random testing as opposed to scheduled testing does not let employees know the test dates, time, etc. beforehand. Using these for random drug testing would thus be a deterrent to the employees - they fear the risk of being detected. This discourages them to use harmful substances. The regular single-panel kits detect only one drug at a time, and they have to be used multiple times with multiple samples to detect multiple substances. This is time consuming. Whereas these test kits detect 2 to 12 drugs with a single sample. This saves considerable time for the drug administering personnel. Further, they cost employers nominally. As they rule out usage of pph surgery for hemorrhoids kits multiple times for detecting multiple drugs, they reduce the testing costs, and are therefore a good value to employers' money.

Convenient and easy to use: They are pretty simple and easy to use. They do not need any medical professionals to handle them. They need a single test sample, either urine or saliva, that are non-intrusive and cause no inconvenience to employees. They are, thus, convenient to use at workplaces. These kits offered by reputed companies are of great help to employers as they are made as per the standards laid by authorities. Kits that are according to SAMHSA standards and approved by FDA are reliable. Multi-panel drug test kits are thus advantageous to employers for endobronchial blocker of substance abuse/dependence and to take appropriate follow-up action on this behalf to ensure a healthy and safe environment, and optimal productivity at workplace.
