FAQ for Drug and Alcohol Screenings


How is the screening done?

The test involves collecting and analyzing a sample provided through normal urination. We recommend that you have something to drink one to two before coming for your drug test but not too much as that will dilute the specimen and you may have to return for further testing.

Why the test is performed?

The test is performed to detect the presence of illegal (and some prescription) substances in your urine, which indicates recent use. The purposes of most drug testing (pre-employment, post-accident, school, random) is to detect the presence of drug use which can negatively impact your job performance or candidacy.

What do “Normal Results” mean?

No drugs were detected in the urine.

What do “Abnormal Results” mean?

If the test result is positive, it is helpful to confirm it with gas-chromatography mass spectrometry (GC-MS). In some cases, a first test will register a false positive. This can result from interfering factors such as some foods, prescription medications, and other drugs.

Will medicines/ substances make my drug test abnormal/ positive?

Some medications and substances can make a screening test turn positive; a confirmation test would then be performed by GC-MS (see above) which would then test specifically for the substance that had screened positive. This test will confirm whether the test is positive or negative.

What is a Medical Review Officer?

A Medical Review Officer (MRO) is a licensed physician who is an expert in drug and alcohol testing and in the application of federal regulations to the testing process.

Will second hand smoke make my test positive?

No, second hand smoke does not cause levels that would trigger a positive test.

What drugs are you testing for?

DOT currently requires “5 panel” testing: marijuana, amphetamines, PCP, opiates, cocaine, MDMA, MDA and MDEA. Alcohol testing for DOT is also required. Some employers may also test for barbiturates, benzodiazepines, methadone, methaqualone and/or propoxyphene.
