On Monday, November 20, 2023, Corewell Health Laboratories West will adjust several hematology result components units of measure. The numerical results will be unchanged, the metric units will be adjusted to achieve standardization across the system and will align our labs with the International Society of Laboratory Hematology’s recommendations for standardization of hematology reporting units in blood counts.
The following parameter will be adjusted because of this change:
White Blood Cell (WBC) currently x10^3/uL will update to x10^9/L
Red Blood Cell (RBC) currently x10^6/uL will update to x10^12/L
Platelets currently x10^3/uL will update to x10^9/L
White Blood Cell (WBC) Automated and Manual Differential Absolute Counts (example: Neutrophil Absolute Count): currently x10^3/uL will update to x10^9/L
Nucleated Red Blood Cell (NRBC) Absolute Count currently x10^3/uL will update to x10^9/L
Immature Platelet Fraction (IPF) Absolute Count currently x10^3/uL will update to x10^9/L
Absolute Reticulocyte Count currently x10^3/uL will update to x10^9/L
