I am an adult male with a red blood cell count of 5.46 ×10⁶/µL, hemoglobin 16.4 g/dL, and hematocrit 50%; are these values normal and do I need any further evaluation or treatment?

Your Values Are Normal and No Further Evaluation Is Needed

Your red blood cell count (5.46 ×10⁶/µL), hemoglobin (16.4 g/dL), and hematocrit (50%) all fall within the normal reference ranges for adult males, and you do not require any treatment or additional testing at this time. 1

Normal Reference Ranges for Adult Males

  • Hemoglobin: The normal range for adult males is approximately 13.5–17.5 g/dL; your value of 16.4 g/dL is well within this range. 1
  • Hematocrit: The normal range for adult males is approximately 41–53%; your value of 50% is normal. 1
  • Red blood cell count: The normal range for adult males is approximately 4.5–5.9 ×10⁶/µL; your value of 5.46 ×10⁶/µL is normal. 1, 2

When These Values Would Be Abnormal

Polycythemia Vera Screening Thresholds

  • According to the NCCN 2016 guidelines, polycythemia vera (a myeloproliferative disorder) is considered only when hemoglobin exceeds 16.5 g/dL in men or hematocrit exceeds 49% in men. 3
  • Your hemoglobin of 16.4 g/dL is below the 16.5 g/dL threshold, and your hematocrit of 50% is only marginally above 49%, which does not meet diagnostic criteria for polycythemia vera without additional clinical findings. 3
  • Diagnosis of polycythemia vera requires meeting either all three major criteria (elevated hemoglobin/hematocrit, bone marrow biopsy showing hypercellularity, and presence of JAK2 mutation) or the first two major criteria plus a minor criterion (subnormal erythropoietin level). 3

Anemia Thresholds

  • Anemia in adult males is defined as hemoglobin below 13.0 g/dL; your value of 16.4 g/dL is well above this threshold. 3

Clinical Context Matters

  • The relationship between hemoglobin and hematocrit can vary slightly with age and individual physiology, but your values are internally consistent and normal. 4
  • Complete blood count parameters—including red blood cell count, hemoglobin, and hematocrit—show normal physiologic variation throughout adulthood, and your values reflect healthy erythropoiesis. 2

No Action Required

  • You do not need transfusion, phlebotomy, bone marrow biopsy, JAK2 mutation testing, or any other hematologic intervention. 3
  • Routine follow-up with your primary care provider is appropriate, but no urgent or specialized hematology evaluation is indicated based on these values alone. 1, 2
