Intravenous fluids cause systemic bias in a conductivity-based point-of-care hematocrit meter.

Abstract

Dilution of blood with frequently used IV solutions affects whole blood conductivity determinations and thereby decreases hematocrits measured by a POC device relying on this method as compared with spun hematocrit. Conductivity-based hematocrit POC devices should be cautiously interpreted when hemodilution is present.
