No, The USCG will only accept a DOT 5 Panel Drug test conducted according to 49 CFR part 40 that is reported as ‘‘negative’’ by an MRO.

Man holding USCG MMC, highlighting the drug test process for USCG license requirements, including handling a Negative Dilute.

This means that a completed drug test form (Federal Drug Testing Custody and Control Form or CG-719P) must be signed by a Medical Review Officer (MRO) showing the applicant has passed a DOT 5 Panel Drug test with a negative result.

In the eyes of the USCG, Passing a DOT 5 Panel Drug test for dangerous drugs only means that the result of a DOT 5 Panel Drug test conducted according to 49 CFR part 40 was reported as ‘‘negative’’ by a MRO.

The National Maritime Center will not accept any other result - including “negative – dilute” or “positive”. They will also not accept any other drug test, only the DOT 5 Panel Drug test called out in 49 CFR part 40.

If you get the wrong test by accident go back to the clinic and ask for the correct Drug Test. This guide will help make it easy!
