A Hematocrit Primarily Measures the Volume of ________

Question

A hematocrit primarily measures the volume of ________.
A) platelets
B) red blood cells
C) white blood cells
D) oxygen

Accepted Answer

A hematocrit measures the volume or percentage of red blood cells in the total blood volume. It is used to diagnose conditions such as anemia and polycythemia. Platelets and white blood cells are not measured by a hematocrit, and while oxygen is carried by red blood cells, a hematocrit does not directly measure oxygen.
