Medications and substances

Cross-reactions

Certain medications can cause positive results on drug tests, even though the person is not abusing drugs. This is called a cross-reaction and is important to know about to avoid misunderstandings. Below you will find an overview of common medications and which substances they can cross-react with in rapid tests.

What are cross-reactions?

Cross-reactions mean that certain medications can give false positive results on drug tests, even though the person has not used narcotics. This is because the medication contains substances that are chemically similar to drugs.

For positive drug tests in the workplace, an MRO physician always conducts a medical review and may contact the employee to determine if the result can be explained by, for example, prescribed medications before it is confirmed as positive.
For positive drug test results, it is always recommended to verify the sample through laboratory analysis. Rapid tests work well as initial screening, but results can be affected by cross-reactions from prescribed medications. Laboratory verification ensures a reliable, accurate, and legally sound result, which is crucial in both the workplace and healthcare settings.

Important information

It is important to understand how cross-reactions are handled in our tests

MRO physicians review all results

A Medical Review Officer (MRO) reviews all positive results before they are reported. This ensures that prescribed medications are not mistakenly interpreted as abuse.

Inform about medications

Employees should always inform the sample collector about any prescribed medications. This speeds up the process and avoids misunderstandings.
