what is the principle of the sedimentation rate? (ESR)
measures the suspension stability of the red cells
what are the two methods of the ESR (sedimentation rate)?
westergren and wintrobe
what is the normal value in the ESR for males and females?
M: 0-15 mm/hr F: 0-20 mm/hr
how do you calculate MCV
mean corpuscular volume= average size of red blood cell (Hct/RBC in millions) X 10
