Which of the following statements is incorrect regarding a hematocrit:

a manual hematocrit is an underestimation of the true value which is obtained via the automated method
it is the percentage of RBCs in sample of whole blood
it provides an indication of the oxygen-carrying capacity of an individual
it is the packed cell volume divided by the volume of a whole blood sample

Which of the following is incorrect regarding a packed cell volume (PCV):

PCV is not the same thing as a hematocrit
a person with anemia will likely have a lower PCV than a normal person
if you are dehydrated, you will have a higher PCV than normal
blood doping leads to an increased PCV
