“Easy-to-Remember Tips for MCV
1.MCV (MCV < 80 fL) (Microcytic Anemia)
think of ‘ Iron deficiency ‘ or ‘ Thalassemia ‘.
Memory Trick: ‘TAILS‘
- T: Thalassemia
- A: Anemia of chronic disease (sometimes microcytic)
- I: Iron deficiency anemia
- L: Lead poisoning
- S: Sideroblastic anemia
2.MCV (MCV 80-100 fL) (Normocytic Anemia)
think of ‘Blood loss,’ ‘Red blood cell destruction,’ or ‘Bone marrow failure.’
Memory Trick: ‘ HAM ‘
- H: Hemolysis (red blood cell destruction)
- A: Acute blood loss
- M: Marrow failure (aplastic anemia)
3.MCV (MCV > 100 fL) (Macrocytic Anemia)
think of ‘B12/Folate deficiency,’ ‘Liver disease,’ ‘Alcoholism,’ or certain ‘Genetic disorders.’
Memory Trick: ‘ BIG FAT RBC ‘
BIG
- B: B12 deficiency
- I: Increased reticulocytes (e.g., in hemolysis or blood loss recovery)
- G: GI malabsorption (leading to B12/folate deficiency)
FAT
- F: Folate deficiency
- A: Alcoholism
- T: Thyroid disease (hypothyroidism)
RBC
- R: Reticulocytosis
- B: Bone marrow disorders (myelodysplastic syndromes)
- C: Cirrhosis (liver disease)”
