Most labs do this test within one day and send the report to the people who ordered it within 24 hours for a total of 24-48 hours between when a sample is given and when the report arrives.

what would cause a delay in the employer getting results within 24-48 hours?
Expert:  Doctor Marcus replied 7 years ago.
It depends on the lab, but there might have been a positive result which they are confirming with an additional test. Or, it could just be a clerical error.

how long will it take for results if it is positive?
Expert:  Doctor Marcus replied 7 years ago.
This will probably take another day or two. Often, the confirmatory test is called a GC/MS or TLC and is a bit more complicated than the regular urine test.
Customer: replied 7 years ago.
so if a test was done friday feb 26th, then the employer should have the results by now correct?
Expert:  Doctor Marcus replied 7 years ago.
Most likely. You could always call the lab and make sure the specimen wasn't lost or anything like that.
