Hi

Thanks for the answer. So there is no chance of false posotive from st. johns?

Hi there

 

No one will test specifically for St John's Wort, but by taking St John's Wort, it can cause you to have a false-positive for things like Benzodiazapines.

Since there can be a false-positive, yes, I think it would be in your best interest.

As a physician trained and certified as a Medical Review Officer (MRO) - the physicians involved in the interpretation of drug tests required for DOT and other federal drug testing programs, I am concerned that the answer you were provided may be misleading.

While some SCREENING tests for drugs may result in a "false positive", the legally defensible drug testing programs routinely conducted by employers are required to use a confirmation test (typically GC/MS) - basically a "chemical fingerprint" that is specific for the drugs tested.

St. Johns Wort would NOT cause a false positive on any drug test that was conducted in accordance with federal guidelines which mandate GC/MS confirmation.
