Master-Med LLC offers a variety of DOT and Non-DOT services. From drug tests to medical cards. Services are available for everyone: truck drivers, bus drivers, warehouse workers, limo drivers, school bus drivers, new employees, etc. DOT services are federally mandated and results are always reported appropriately. Non-DOT services are not federal, meaning that they do not get reported anywhere but to your employer. (You can always do a drug test or alcohol test for yourself as well. These results no one sees but you). All services are available nationwide. Nationwide drug testing, nationwide alcohol testing, nationwide medical card / physicals. Each service will explained in more detail below.

Drug Test

Master-Med LLC offers a variety of different drug tests for any reason. Most common drug tests done are pre-employment and random drug tests. A pre-employment drug test is usually required for a lot of companies before they hire you. Truck drivers are required to take a pre-employment drug test every time they start at a new trucking company. This includes if you are opening up your own MC and DOT. You are still required to take a pre-employment drug test. Every trucking company needs to do random drug tests for their drivers as well. FMCSA requires this, and provides specific guidelines. Master-Med LLC can help you with the random drug and alcohol tests and make sure that you are always compliant and following FMCSA guidelines. Additionally to the pre-employment and random drug tests, Master-Med LLC also offers return-to-duty, observed, post-accident drug tests. Observed drug tests can be DOT or Non-DOT, but the process is the same. Master-Med LLC also offers instant (or rapid) drug tests. These tests are not sent to the lab and could be less accurate, but it is an easy and quick way of checking if you have any drugs in your system. (Rapid test is only a 5-panel at our locations).

Alcohol Test

Master-Med LLC offer DOT and Non-DOT alcohol testing. There are usually three ways of checking for alcohol in a persons body. These are a blood collection, urine collection, or a breathalyzer test. Master-Med LLC only offers breathalyzer alcohol tests, as this is the most common form of testing and it is the only form of DOT alcohol testing. In terms of DOT and Non-DOT, the alcohol testing is the same exact thing. The only difference is that the DOT test is federal, just like the drug test, and the Non-DOT test is not federal. This means that the alcohol test will also get reported federally, while the Non-DOT alcohol test will not get reported anywhere (other than to your employer).
