We will be implementing an important update to our system over the weekend. Unfortunately, this means the system will be down over the weekend, 10/26-10/27.
As a result, there may be some delays in the processing of specimens. We appreciate your understanding and patience during this time. If you have any questions, please feel free to contact us.
