Hematology

Question 1

Normal Hemoglobin levels for men and women

Answer 1

Males: 14.0 to 18.0 g/dL

Females 12.0 to 16.0 g/dL

Question 2

Normal Hematocrit levels for men and women

Answer 2

Males: 42% to 52%
Females: 37% to 47%

Question 3

Normal MCV (mean corpuscular volume)

Answer 3

Normal: 80 to 100 fL (femtoliter)
MCV < 80 = microcytic anemia
MCV 80-100 = normocytic anemia
MCV > 100 = maceocytic anemia

Question 4

Normal Mean Corpuscular Hgb Concentration (MCHC) levels

Answer 4

Average color of RBCs in blood sample

Normal: 31.0 to 37.0 g/dL

Question 5

Normal Mean Corpuscular Hemoglobin

Answer 5

Indirect measure of RBC color

25.0 to 35.0 pg/cell

Question 6

Normal Total Iron-Binding Capacity (TIBC)

Answer 6

250 to 410 mcg/dL

Decreased with iron-deficiency anemia

Question 7

Normal serum ferritin

Answer 7

Stored form of iron
Most sensitive test for iron-deficiency anemia
Normal: 20 to 40 ng/mL

Question 8

Normal serum iron

Answer 8

Normal: 50-175 mcg/mL

Question 9

What does Red Cell Distribution (RDW) measure?

Answer 9

Measures variability of size of RBCs in blood sample.

Elevated in iron-deficiency anemia and thalassemia

Question 10

Normal reticulocyte count

Answer 10

0.5 to 2.5% of total count

Immature RBCs

Question 11

Normal WBC count

Answer 11

Normal WBC: 5.0 to 10.0 
Neutrophils: 55% to 70%
Band forms (immature neutrophils): 0% to 5%
Lymphocytes: 20% to 40%
Monocytes: 2% to 8%
Eosinophils: 1% to 4%
Basophils: 0.5 to 1%

Question 12

What are the lab findings for iron deficiency anemia?

Answer 12

Decreased:
Hemoglobin and hematocrit
MCV < 80 fL
MCHC (paler color)
Ferritin and serum iron level

Increased:
TIBC (total iron binding capacity)
RDW

Question 13

What is the diagnostic test for thalassemia and sickle cell anemia?

Answer 13

Hemoglobin electrophoresis
