Normocytic: MCV 80-100 fL

Cells should be about the size of the nucleus of a small resting lymph (80-100 fL)

Normochromic: MCHC 32-36 g/dL

Central pallor should be less than 1/3 of the RBC

RDW increased (variation in cell size)

May have dimorphic cell population.

MCV < 80 fL (decreased)

Seen in Iron Deficiency Anemia, Anemia of Chronic Inflammation, Sideroblastic Anemia, Thalassemia

MCV > 100 fL

If cells Is polychromatophilic, it may be a retic. See polychromatophilia for more info.

MCHC <32 g/dL (decreased)

Increased central pallor.

Usually (but not always) microcytic

Seen in Iron Deficiency Anemia, Sideroblastic Anemia, Anemia of Chronic Inflammation, Thalassemia
