Hematology Flashcards
what is the oxygen component of blood
Hb
where is Hb found
RBC’s
what is the % of red cell mass in a unit of blood determined by centrifuging a sample
HCT
what is an indirect estimate of RBC’s in a volume of blood
HCT
what makes up 1/3 of the cells volume
Hb
RBC x 3 =
Hb
Hb x 3 =
HCT
RBC’s x 9 =
HCT
gives the average SIZE of an RBC
mean corpuscular volume (MCV)
estimates the quantity of Hb in an average red cell
mean corpuscular hemoglobin (MCH)
estimates the average concentration of Hb in the average cell. state another way the color of the average cell
mean corpuscular hemoglobin concentration (MCHC)
done with electronic counters, creates a histogram of cell size and shapes (anisocytosis and poikilocytosis) as they relate to the MCV
RBC distribution width (RDW)
done to visualize cell color, shape or make counts of specific cells in circulation
peripheral blood smear
large cells
macrocytes
small cells
microcytes
an increase in the central clear area of the RBC
hypochromia
a type of microcyte that is round and lacks the central clear area
spherocytes
reticulocytes, immature RBC’s
polychromatophilic RBC’s
RBCs partially adhering to each other like a stack of coins and a host of others that will come up in the lecture
rouleaux
number of different white blood cells make up the total count
WBC
determination of the amount of platelets available for inclusion in the clotting process
platelet count
