Question 1: ALL of the following are indications of anemia, EXCEPT which one?
Answer: Decreased PLT
Question 2: Which one of the patient's lab results are not consistent with anemia?
Answer: Toddler HGB: 12.5 g/dL
Question 3: The following results were obtained from a CBC specimen: WBC 10.3 x 10^9/L MCV 95 fl
RBC 4.19 x 10^12/L MCH 33.2 pg HGB 9.9 g/dL MCHC 33.1 % HCT 27.0% What is the most
probable cause of these results?
Answer: Anemia
Question 4: To calculate the mean corpuscular volume (MCV), what parameters must be known?
Answer: RBC and HCT
Question 5: Given the following lab results, what is the calculated MCH? RBC 3.01 x 10^12/L HGB 9.4
g/dL HCT 27.5%
Answer: 31.2pg ((HGB/RBC) x 10)
Question 6: What is the calculation for MCH?
Answer: MCH = ((HGB/RBC) x 10) Expressed in pg. Denotes HGB content in one cell. Normal 27-33pg.
Question 7: What is the calculation for MCV?
Answer: MCV = ((HCT/RBC) x 10) Mean corpuscular volume (MCV) is the average volume of red cells in
a specimen.The reference range for MCV is 80-96 fL/red cell in adult.
Question 8: What is the calculation for MCHC?
Answer: MCHC = ((HGB/HCT%) x 100) Measure of the concentration of hemoglobin in a given volume of
packed red blood cells. Reference ranges are 32 to 36%.
Question 9: What is the reference range for the mean corpuscular hemoglobin concentration?
Answer: 32%-36%

bone marrow?
Answer: Reticulocyte count
Question 13: To calculate the reticulocyte production index, other than the reticulocyte count (%),
what other hematological parameter is needed?
Answer: HCT
Question 14: What are erythrocytes with a diameter of 9-12 microns referred to as?
Answer: Macrocytes
Question 15: What causes the red cell color of immature erythrocytes to appear polychromatophilic?
Answer: Residual RNA
Question 16: What is abnormal variation in the shape of erythrocytes known as?
Answer: Poikilocytosis
Question 17: What does the peripheral blood smear show in a patient with iron deficiency anemia?
Answer: Microcytic, hypochromic cells with poikilocytosis present
Question 18: Which one of the following is a characteristic finding in iron deficiency anemia?
Answer: Low ferritin, low iron, high TIBC, high transferrin
Question 19: Which RBC shows a peripheral rim of hemoglobin with a dark staining central area?
Answer: Leptocyte (also known as a Target cell)
Question 20: Target cells are present in ALL of the following conditions:
Answer: Thalassemia, liver disease, and postsplenectomy
