Do the lab results (RBC 4.23 ×10^12/L, hemoglobin 12.4 g/dL, hematocrit 38.3 %, MCV 90.5 fL, RDW 13 %, platelet count 241 ×10^9/L, serum iron 89 µg/dL, total iron‑binding capacity 235 µg/dL, transferrin saturation 38 %, ferritin 215 ng/mL) indicate anemia and, if so, what type?

No Anemia Present – These Labs Are Normal

Based on these laboratory values, there is no anemia present. The hemoglobin of 12.4 g/dL falls within the normal range for adult females (typically ≥12 g/dL) and is above the threshold for males if this patient is male 1.

Analysis of the Complete Blood Count

Your CBC parameters are all within normal limits:

  • RBC count (4.23 ×10^12/L): Normal
  • Hemoglobin (12.4 g/dL): Normal (not anemic)
  • Hematocrit (38.3%): Normal
  • MCV (90.5 fL): Normocytic (normal size red cells, 80-100 fL range)
  • RDW (13.0%): Normal (indicates uniform red cell size)
  • Platelet count (241 ×10^9/L): Normal

The normocytic MCV rules out microcytic anemias like iron deficiency or thalassemia, which typically present with MCV <80 fL 2, 3. The normal RDW (13.0%) indicates no significant variation in red cell size, which further argues against iron deficiency—where RDW is typically elevated (>14-15%) even in early stages 4, 5, 6.

Iron Studies Interpretation

Your iron parameters are completely normal and actually indicate adequate iron stores:

  • Serum iron (89 µg/dL): Normal (60-170 µg/dL range)
  • TIBC (235 µg/dL): Normal (240-450 µg/dL range)
  • Transferrin saturation (38%): Excellent—well above the threshold for iron deficiency (typically <16-20% suggests deficiency) 1
  • Ferritin (215 ng/mL): Robust iron stores—far above the iron deficiency threshold of <15-25 ng/mL 1, 7

Clinical Significance

No further workup for anemia or iron deficiency is indicated. These values represent a healthy hematologic profile with adequate iron stores for erythropoiesis.

Key Points:

  • Ferritin >200 ng/mL indicates substantial iron reserves
  • Transferrin saturation of 38% demonstrates excellent iron availability for red cell production
  • The combination of normal MCV and normal RDW effectively excludes iron deficiency anemia, which would show MCV <80 fL and RDW >14-15% 3, 6
  • All three cell lines (RBC, WBC implied normal, platelets) are normal, indicating healthy bone marrow function 1

No treatment or additional testing is needed unless clinical symptoms suggest otherwise or there are specific risk factors not reflected in these laboratory values.
