Lab Values Flashcards
normal RBC for men
4.7 - 6.1
normal RBC for women
4.2 - 5.4
a measure of the average volume or size of a single RBC
mean corpuscular volume (MCV)
which part of RBC is used to classify anemia
MCV
increased MCV =
macrocytic anemia
decreased MCV =
microcytic anemia
measure of the average amount (wt) of hgb w/in a RBC
mean corpuscular hgb (MCH)
a measure of the average concentration (density) or % of hgb w/in a single cell
mean corpuscular hgb concentration (MHCH)
measures how tightly the hgb is packed within a RBC
