Anemia Classification

Instructions:

For each of the scenarios below, identify the following:

1. Type of anemia a. Folate Deficiency b. Anemia of Inflammation c. Iron Deficiency Anemia d. Vitamin B12 Deficiency e. Thalassemia

2. Classification of anemia a. Microcytic-hypochromic b. Macrocytic-normochromic c. Normocytic-normochromic

3. After identifying the type and class, describe the pathophysiology of each of the anemias.

Use the following normal CBC ranges

WBC 4500-11,000/mm³

RBC Male: 4.3-5.9 million/mm³ Female: 3.5-5.5 million/mm³

Hemoglobin Male: 13.5-17.5 g/dL Female: 12.0-16.0 g/dL

Hematocrit Male: 41%-53% Female: 36%-46%

Mean corpuscular volume 80-100 µ³

Mean corpuscular hemoglobin concentration 32-36 g/dL

Serum iron Males: 50-150 mcg/dL Females: 35-145 mcg/dL

Ferritin Males: 30-400 ng/mL Females: 13-150 ng/mL

Total iron-binding capacity 240-450 mcg/dL
