Here is the complete RBC reference data from Goldman-Cecil Medicine (authoritative textbook source):
RBC Normal Range - Both Sexes

| RBC Count | 4.0 - 5.4 × 10⁶/µL | 4.5 - 6.0 × 10⁶/µL |
| Hemoglobin | 12 - 16 g/dL | 13.5 - 17.5 g/dL |
| Hematocrit | 36 - 48% | 40 - 52% |
| MCV | 81 - 99 fL (both) | 81 - 99 fL (both) |
| MCH | 30 - 34 pg (both) | 30 - 34 pg (both) |
| MCHC | 30 - 36 g/dL (both) | 30 - 36 g/dL (both) |
| RDW-CV | 12 - 15% (both) | 12 - 15% (both) |
| RDW-SD | 37 - 47 fL (both) | 37 - 47 fL (both) |

Key Points
- Males have higher RBC counts than females due to testosterone's stimulatory effect on erythropoiesis.
- The difference also explains why men have higher hemoglobin and hematocrit values.
- Values are for adults; pediatric ranges differ by age.
- Note: Mayo Clinic uses slightly narrower ranges (men: 4.35-5.65, women: 3.92-5.13 × 10⁶/µL) - small lab-to-lab variation is normal.
- Values below these ranges suggest anemia; values above may indicate polycythemia.
