ANEMIA Flashcards
memorization (36 cards)
Decreased RBC, Hb, and Hct; Result in a reduction in the oxygen-carrying capacity of the blood and subsequent hypoxia
Anemia
Hypochromia grading; Area of central pallor is one-half of cell diameter

Numerical scale: Normal appearance of slight variation in erythrocytes
0
Numerical scale: only a small population of erythrocytes displays a particular abnormality. the terms INCREASED or FEW would be comparable
1+
Numerical scale: Severe increase in abnormal erythrocytes in each microscopic field; an equivalent descriptive term is MANY
3+
Numerical scale: More than occasional numbers of abnormal erythrocytes can be seen in a microscopic field: an equivalent descriptive term is MODERATELY INCREASED
2+
Numerical scale: The most severe state of erythrocytic abnormality, with the abnormality prevalent throughout each microscopic field; comparable terms are MARKED or MARKED INCREASE
4+
RBC indices which refer to the measure of average concentration of hemoglobin
MCHC
RBC indices which refer to the measure of average weight of hemoglobin
MCH
ROULEAUX GRADING: aggregates of 3-4 RBCs
1+/SLIGHT
ROULEAUX GRADING: 3+/MARKED
NUMEROUS AGGREGATES WITH ONLY FEW FREE RBCs
ROULEAUX GRADING: aggregates of 5-10 RBCs
2+/MODERATE
Derived from RBC histogram; coefficient of variation of the MCV
Red Cell Distribution Width (RDW)
RDW is _____ proportional to the degree of anisocytosis
Directly proportional
Which of the following is not a computed value by the machine?
A. RBC
B. RDW
C. HCT
D. MCHC
A. RBC
- RDW, HCT, MCHC along MCH are computed values by the machine.
- RBC, WBC, Platelets are directly measured by the machine (counted)
Term for size variation
Anisocytosis
