BASIC HEMATOLOGIC TESTS Flashcards
what are the basic hematologic tests?
hemoglobin hematocrit erythrocyte count wintrobe indices -mean cell volume -mean cell hemoglobin -mean cell hemoglobin concentration red cell distribution width
transport protein which is the transport vehicle for oxygen and CO2
measured spectrographically
males 14-18
female 12-16
hemoglobin
ratio of the volume of erythrocytes to that of whole blood
automated-calculated from MCV and RBC
reference range
males 41-53%
females 36-46%
hematocrit
expressed as the number of cells per unit volume of whole blood
automated
electrical impedance
light scattering
erythrocyte count
wintrobe indices?
mean cell volume
mean cell hemoglobin
mean cell hemoglobin concentration
what is this wintrobe indice?
the average volume of the red cells, measured in femtoliters; important for anemias and hemoglobinopathies
MCV=HCT/RBC
reference range- 76-96 fl
mean cell volume (MCV)
what is this wintrobe indice?
the content of hemoglobin of the average red cell, measured in picograms
MCH=HGB/RBC
reference range- 27-33 pg
mean cell hemoglobin (MCH)
what is this wintrobe indice?
the average concentration of hemoglobin in the given volume of packed red blood cells
MCHC=HGB/HCT
reference range- 30-35 g/dl
mean cell hemoglobin concentration (MCHC)
measure of the variability of MCV distribution
increased in conditions with large variation in red cell size
early indicator of iron deficiency
red cell distribution width (RDW)
