For automated hematologic analyzers (LH 750), the RBC and MCV are directly measured by the instrument depending on the number of pulses for RBC and the amplitude of each pulse for MCV using electronic impedance; then the hematocrit is calculated by using following equation:
In summary, the authors allege that a positive bias in SureStep[R]Flexx[R] measurement at low hematocrit values contributed to hypoglycemic episodes in the NICE-SUGAR study, but they do not present supportive evidence.

Q We have several physicians who are questioning hematocrit results.
"If this association is causal, normalization of hematocrit in this population would be expected to reduce mortality by approximately 33%, based on the magnitude of risk observed in our study--or one less annual death for every eight patients successfully treated."
