CBC and anemia Flashcards
Female Hgb
12-14 g/dL
male hgb
14-16 g/dL
female Hct %
36-43
male Hct %
42-48%
Hgb g to %
10 g = 30%
12 g = 36%
15g = 45%
MCV microcytic
small cell, MCV < 80 fL
MCV macrocytic
abnormally large cell, MCV > 100 fL
Normocytic:
normal cell, MCV 80-100 fL
MCH ~
MCHC ~
Mean Cell Hemoglobin
Mean Cell Hemoglobin Concentration
Vitamin B12~Pernicious Anemia ~ Folate-Deficiency
macrocytic, normochromic w/high MCV
Abnormally large RBC d/t altered RNA:DNA ratio, hgb usually normal; new RBC larger than old ones elevated RDW Usu. Hgb, hct, rbc – all slightly low; mcv usu elevated, rdw – elevated
Hypochromic:
pale, MCHC=<31 g/dL
What is the rdw?
Red Blood Cell Distribution Width
Index of variation in RBC size
Normal = 11.5%-15%
RDW >15%,
indicating that new cells differ in size (smaller or larger) compared with older cells
This is one of the earliest laboratory indicators of an evolving microcytic or macrocytic anemia
what are steps for diagnosing anemia
Review current laboratory results looking at Hgb/Hct first
- IF there is an abnormal level, HOW abnormal is it?
- NEXT, review trends over time . . .
- THEN, look at the MCV .
