Spectrum Health has been informed by Roche Diagnostics that the proprietary reagents used to calibrate our instruments and determine control values for ferritin blood level have been updated to reflect deviation of results leading to low result bias. This may have led to patient results being up to 20% lower than actual ferritin level.

As of January 12, 2016, pathologist review of peripheral blood smear ordered without accompanying CBC with differential will reflex to adding on a CBC and/or differential in the laboratory. Blood specimens that do not have a slide prepared need to be less than 6 hours old for a pathologist review to be added on.
This is due to the fact that older blood does not smear well and morphology is compromised, especially red cell morphology. This allows for a complete documentation of the patient’s CBC and differential findings in the electronic medical record and standardizes our process among the regional hospitals.
Any questions concerning Peripheral Blood Smear reflexes should be directed to Dr. Jennifer Stumph, Director of Hematology.
