Lab Specimen Label Printing Update for Corewell Health Epic Users

On 10/31/23, a change was made to lab specimen labels, which included a patient’s preferred name on the label, if it is documented in Epic. This highlighted a change in the names of label types seen by staff when reprinting specimen labels in Epic. Due to a mix of Intermec and Zebra printers across the entire Corewell Health system, defaults needed to be removed from Epic build to account for these differences. Users will now be required to manually choose the correct label type when reprinting labels. The Collection Activity behavior should remain the same. Continue Reading

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/

Influenza Testing Recommendation (December 2023)

Influenza cases numbers are currently increasing throughout West Michigan. Influenza prevalence guides the most appropriate testing approach and sufficient prevalence has now been reached for influenza rapid antigen or point of care testing (e.g. Sofia instrument) to have improved performance. The use of point of care testing as a screening method during high prevalence reduces both the cost to the patient and turn-around-time as compared to lab-based molecular methods. Point of care tests generally have high analytical specificity, but lack the sensitivity of nucleic acid amplification methods (e.g. PCR). For this reason, PCR testing is still recommended for hospitalized patients and for outpatients with a negative result if influenza is still suspected and if the result will impact clinical decision making.
