Red cell indices -Provide information in the size and
hemoglobin
content of the RBCs.
-Uses include: differentiating anemias and
predicting morphology related to disease
states.
-Uses RBC count, Hgb and Hct
Mean Corpuscular Volume (MCV) -Measured in femtoliters; Hct/RBC x 10
-Relates to cell size. Normal = 80-100fl.
-Microcytic: MCV < 80fl
-Macrocytic: MCV > 100fl
Mean Corpuscular Hemoglobin -average weight of hemoglobin in red cells.
(MCH) -Measured in picograms. Hgb/RBC x 10.
Normal =
27-33 pg.
, Mean Corpuscular Hemoglobin -Concentration of hemoglobin in the RBCs
Concentration (MCHC) relative
to their size.
-g/dL or %, Hgb/Hct x 100. Normal =
33-36%
Normachromic.
->36% is hyperchromic, most often from
incorrect
calculation or agglutination of patient
RBCs.
-<33% is hypochromic, due to decreased
hemoglobin.
Red Cell Distribution Width (RDW) Measure of the variability of the size of
RBCs. If
more than 15% then sample contains cells
that are
different in size - anisocytosis.
poikilocytosis Variation in shape of RBCs
erythrocyte sedimentation rate -Rate at which RBC's settle out of the
(ESR) plasma under
a set of controlled laboratory conditions.
-Anticoagulanted blood is placed in tube of
standard dimension, incubated at room
temperature in vertical position, read
distance the
RBCs fall.
-Measured top to bottom in mm/hr.
