Effective March 1, the laboratory is updating the methodology for Sedrate testing.
The new Alifax Sedrate analyzer will improve the requirements for testing time, specimen volume and specimen stability (see below). With this change the Normal Range results will be adjusted (see below). A notification will be appended to Epic results for the first three months as a reminder of changes to the Normal Range.
