Last November attempted to renew my Merchant credentials. The required drug test was to be forwarded directly to the Coast Guard. I recently received notice that the test results were never received and the grace period for renewal had lapsed. I now must re-submit over 20 pages of documents, update my sea time and have a new druig test done and pay a new renewal fee. I am notifying the Coast Guard of LabCorps' incompetence and suggest they reconsider accepting any documents from this company.
