How long does it take to get drug test results?

This will depend on the test required, when the collection appointment is set and the results. Most often tests are scheduled by the donor within a few days of the order submission and results are returned within several days from that time. A negative result is normally returned within 48 hours of collection. If there is any need for additional information, or there is a non-negative result, the donor may be contacted by the Medical Review Officer which takes additional time.
