Test Performed in the Hematology Section Flashcards
Differential (Diff)
Determines the percentage of the different types of white blood cells and evaluates red blood cell and platelet morphology (may be examined microscopically on a peripheral blood smear stained with Wright’s stain)
Hematocrit (Hct)
Determines the volume of red blood cells packed by centrifugation (expressed as a percent
Hemoglobin (Hgb)
Determines the oxygen-carrying capacity of red blood cells
Indices
Calculations to determine the size of red blood cells and amount of hemoglobin
Mean corpuscular hemoglobin (MCH)
Determines the amount of hemoglobin in a red blood cell
Mean corpuscular hemoglobin concentration (MCHC)
Determines the weight of hemoglobin in a red blood cell and compares it with the size of the cell (expressed as a percent)
Mean corpuscular volume (MCV
Determines the size of red blood cells
Platelet (PLT) count
Determines the number of platelets in circulating blood
Red blood cell (RBC) count
Determines the number of red blood cells in circulating blood
Red cell distribution width (RDW)
Calculation to determine the differences in the size of red blood cells (expressed as a percent)
White blood cell (WBC) count
Determines the number of white blood cells in circulating blood
Body fluid analysis
Determines the number and type of cells in various body fluids
Bone marrow
Determines the number and type of cells in the bone marrow
Erythrocyte sedimentation rate (ESR)
Determines the rate of red blood cell sedimentation (nonspecific test for inflammatory disorders)
Reticulocyte (Retic) count
Evaluates bone marrow production of red blood cells
