C) RDW-CV reference range: 80-100 fL; RDW-SD reference range: 11-15 g/dL.

D) RDW-CV reference range: 0.5-1.2%; RDW-SD reference range: 12-14 g/dL.

Answer 1

The reference range for RDW-CV is 12-15% and for RDW-SD is 36-46 fL.

Step-by-step explanation:

The reference range for RDW-CV is 12-15%. RDW-CV stands for Red Cell Distribution Width - Coefficient of Variation. It measures the variation in size of red blood cells. A value below the reference range may indicate a more uniform size of red blood cells, while a value above the range may suggest greater variability in red blood cell size.

The reference range for RDW-SD is 36-46 fL. RDW-SD stands for Red Cell Distribution Width - Standard Deviation. It measures the width of the distribution curve of red blood cell size. A higher RDW-SD value may indicate a wider range of red blood cell sizes.
