A falsely elevated Hct will not impact which of the following calculated values?

A falsely elevated hematocrit (Hct) refers to a situation where the measurement indicates a higher proportion of red blood cells in the blood than is actually present. This can happen due to factors such as dehydration or hemoconcentration. It's important to understand how these factors can affect various calculated values in a Complete Blood Count (CBC).

Mean corpuscular volume (MCV) is a measure of the average volume of a red blood cell, and while an elevated Hct could potentially indicate larger cells under some circumstances, it is not directly impacted by a falsely high Hct. This is because MCV is calculated based on the total volume of red blood cells divided by the number of red blood cells, rather than on the proportion of red blood cells in the blood sample.

Mean corpuscular hemoglobin (MCH), which reflects the average mass of hemoglobin per red blood cell, and mean corpuscular hemoglobin concentration (MCHC), which indicates the concentration of hemoglobin in a given volume of packed red blood cells, are both influenced by the hemoglobin content per cell and the overall volume of red cells. Therefore, changes in Hct can affect these values.

Similarly, red cell distribution width (RDW), which measures the variation in red
