We notify you
You will receive a call or email as soon as your result has been reviewed and released.
Access and review your report
Results are shared securely with you and with any employer, agency or court authorized to receive them.
Act on your result
Non-negative results are evaluated by a Medical Review Officer, who will contact the donor privately to discuss any legitimate medical explanation before a result is reported.
A Medical Review Officer is a licensed physician who evaluates every non-negative laboratory result. The MRO contacts the donor privately to determine whether a valid prescription or medical explanation accounts for the finding before any result is reported to an employer, agency or court.
