Reminder: Send Out Referral Testing Notice

As a reminder, referral testing, tests that are sent to another laboratory to perform, is dependent on the weather. Inclement weather can affect both the turnaround time of testing, and the testing capabilities of the organization. Our referral testing is dependent on outside transportation facilities (such as FedEx and UPS). When those organizations face challenges in weather, our testing capabilities must remain flexible. 

If there is inclement weather in and around Memphis, TN (the main FedEx hub), there may be delays and cancellations of testing. We will try our best to communicate these changes as soon as possible via our blog: https://lab.corewellhealth.org/

CSF Priorities on QNS Specimens

When a Cerebrospinal fluid (CSF) specimen arrives into the laboratory and is deemed Quantity Not Sufficient (QNS) for ordered testing, the ordering provider is contacted to identify testing priorities. Occasionally, the laboratory is unable to secure these priorities.

If the lab is unable to secure priorities from the ordering provider within an hour of collection, the following will occur:

1. We will move forward with the Cell count with differential, Culture, and Protein/Glucose

2. The rest of the ordered testing will hold until we can clarify the priorities

Laboratory is partnering with Epic Beaker to discover if a prioritization of orders, upon CSF order entry, is possible.

If you have questions or concerns, please use the “Contact Us” link above.
