Blood Indices Quiz

Which of the following best defines MCV?

• Average weight of hemoglobin per RBC

• Concentration of hemoglobin in RBCs

• Average volume of a single RBC

• Variation in size of RBCs

MCHC is decreased in which of the following conditions?

• Hereditary spherocytosis

• Iron deficiency anemia

• Autoimmune hemolytic anemia

• Polycythemia vera

Which formula is used to calculate MCH?

• (Hgb × 10) / RBC

• (Hct × 10) / RBC

• (Hgb × 100) / Hct

• (RBC × 10) / Hgb

The normal range of MCV is:

• 27–33 pg

• 32–36 g/dL

• 80–100 fL

• 11.5–14.5%

Which of the following affects RDW the most?

• Plasma volume

• Anisocytosis

• Total RBC count

• Leukocyte count

A low MCHC is most likely found in:

• Sickle cell anemia

• Iron deficiency anemia

• Macrocytic anemia

• Aplastic anemia

MCH is usually expressed in:

• grams/deciliter

• grams/liter

• picograms

• femtoliters

Which index reflects the concentration of hemoglobin in the red cells?

• MCH

• MCV

• MCHC

• RDW

An MCV of 72 fL is classified as:

• Normocytic

• Microcytic

• Macrocytic

• Hypochromic

A high RDW with normal MCV suggests:

• Normocytic normochromic anemia

• Early iron deficiency anemia

• Aplastic anemia
